Re: more parts ordered!......(edit) almost done with pics!!!

Not much has been happening, just waiting.

Friday, I ordered me a new stall converter from "the man" that builds them locally here in Columbia, very reputiable. He's building me a new super street converter with 2 anti balloning plates, 2800 to 3000 stall, and I think that'll help me with getting out of the hole!!!

Re: more parts ordered!......(edit) almost done with pics!!!

Man I just noticed - you are right down the street. I live in a little town called Sandy Run kind of toward St. Matthews. I'm assuming you are talking about Cameron - I have nothing but great things to say about him - very knowledgable and helpful. If it keeps beating you, maybe I could stop by one day and help you try to figure it out. Clay

 

Re: more parts ordered!......(edit) almost done with pics!!!

I don't know how I got here, I thought I was posting to 90whitepony about his leaning out problem. Still good to see somebody right down the road though. You gonna run it at the new 'Burg? It looks great and I can't wait for cooler weather. Clay

 

Re: more parts ordered!......(edit) almost done with pics!!!

Hey Clay!

Great to see someone on here that is so close! I work at Carolina Eastman, so I know exactlly where Sandy Run is!!!! Plus Bunkys, Chaps, Pete's store, and several people from that area.

Cameron is the guy who is building my converter, and from what I've heard, he knows his shit. EVERYONE around here that is racing with an auto is using his converters. My brother just picked 2 up from him, one is in his 66 Chevelle, 468bbc.

As far as comming by, you are more than welcome to stop by, and anything that you see at the shop, stays at the shop. I plan on hurting alot of people's feelings around here with this ol truck, plus thier wallets too. I don't want them to know what hit them until it is too late.

As far as the 'burg, I'm not going to run mine. I don't want everyone to see my truck run, it's a sleeper. You know, a stock engine with 4 psi...... I"ll go down there and watch, but just to spectate. Then once I get some money, and everyone gets off my back, then I may run to get some times, hopefully get kicked off the track! If you know where dragstrip road and US 321 intersect (savanaha hy, the one that runs through north, woodford, swansea, gaston), then you are right on top of my house!!

If you like, call me at (803)682-5099. I'll give you directions, and any info that you want to know about my build.

btw...I've noticed, around here, no one running turbos or superchargers get respect, it's all nitrous.......until now! Hehehe. Oh yeah, swing by, and I'll take you to see my friend who has a BEAUTIFUL, yellow 1932 ford coupe, with a blown 350 chevy. You'll love it. Bud light's welcome also!

Re: more parts ordered!......(edit) almost done with pics!!!

Cool, once it cools off a little bit, I'll call you and drive the Nova down one Saturday. I know exactly the location you are talking about. I used to run nitrous and for power on pump gas, I'll never go back. The Procharger is amazing and from what I gather on here, turbo's are more efficient and build boost quicker for more torque. I can't say enough good things about Cameron - you couldn't ask for a nicer person or a smarter transmisson / converter guy. BTW - sorry you are catching hell with the machine shop - that sucks. If you work at Eastman, then we probably know some of the same people. I live pretty close to Teepak on Old Swamp Road, so it'll be a short trip to your house. Later, Clay.

 

Re: more parts ordered!......(edit) almost done with pics!!!

Alright yall, nothing spectacular yet.

1. My converter is getting finished up tommorow. (3000 stall, super street with anti-balloning plates)

2. The engine will be done and I'm picking it up Friday

3. I just ordered a set of Cal-Trac traction bars for the pick-up, so they should be on the way.

The only other thing that I can think of that I need is some good sticky tires (325 X 50 X 15, Micky Thompson's new drag radial) a positive traction unit for the GM 12bolt truck with about 3.23 or 3.55 gears, shift kit for the 375 transmission, and maybe a transbrake later.

I'll keep everyone posted!

Re: more parts ordered!......(edit) almost done with pics!!!



That is skittles, the sleeper!



And skittles's friend, the small 9" converter!

Had a good weekend, got the shortblock back, got the converter, painted everything (drunk, of course....see pic) put long block back together and got it into the truck. Gotta finish the small things tommorow, and we should be back up and running!

We got 50 PSI while prelubbing the engine with the drill!!!

Lot's of duct tape, couple of junk yard yellow lettered add on's, and this thing will look like shit. Think anyone will race this POS in a truck?

Oh yeah, caltrac bars are in also!

Re: more parts ordered!......(Round 2, skittles)!!!

Well,

After a couple of days of getting everything together, took her out for a test drive to watch the gauges and see how she was going to respond to her new heart.

She was idleing ok, A/F ratio was eratic, but ok, right around 13.1, which I was fine with for now. We let it heat up, burn off the grill paint that was on the headers, and down the road we went. Nothing special, just up the road about 3/4 mile, watching the o2 meter, and comming back. O2 was all over the place.

Came back home, shut her down, and looked at everything. The temp gauge on the dash was reading 190 to 200*, but the overflow to the catch can was open, blowing coolant in the catch can like it was running hot. We cooled it down, checked everything again, and we to a friend of mine's house, about 4 miles up the road.

The total timing was locked at 25, and she was a pig. Sluggish, and once we got on it, it would only make 5 lbs of boost with a 10lb spring in the wastegate. Part throttle O2 was lean, idle would go from rich to lean, but WOT was still rich at 11.5:1 to 12.0:1.
When we got to my friends house, the daymn headers and turbo housing was GLOWING red! We were like WTF!!!

Ended up blowing out the header gasket (aluminum), so now we had exhaust leaks and ?????'s about what was going on. We knew it was the timing, or fuel. We bumped the total timing up to 29, and I went back home after it cooled. When I got home, it was GLOWING red again!

This morning, I replaced the header collector gasket. I went out there and pulled the PV out of the metering block, and put a plug in it. Then I stepped up to 78's on the primary jets, and drove it around. It was rich as a pig during small loads, but when the boost would come in, it would lean up some and run like a scalded dog! I bumped the timing up around 32*, and fixed the PV problem, and the glowing headers went away, but left a leaking turbo seal! (oil to the exhaust) Now it's smoking, and I have to pull the turbo. Not only that, but I fried my MSD 6AL BTM box yesterday, and it's off to Texas for a rebuild.

As for the PV problem, I did find a bad vacume leak on the metering block!!! There is a port above the idle mixture screw on the passenger side of the metering block which on mine was wide open!!! No plug or vacume nipple, just open to the atmosphere, so I'm hoping that was some of the problems with the PV and controll problems that I had with this carb. I was getting really agravated with this POS! I've already plugged it, but the turbo was leaking oil, and I figured that oil would get on my wide band O2 sensor and ruin it if I didn't quit, so I stopped there.

She's really getting better, I'm just being really over conservitive with the timing and fuel. As soon as I get the 6AL BTM back, I'll set total timing at 36*, then let the box pull timing out of her when boost comes in, cause from 25 to 32*, this truck has a hole lot better take off, and this thing is a beast under boost!

I'll keep yall posted, WE HAVE A BEAST WAKING UP!

 

Re: more parts ordered!......(Round 2, skittles)!!!

another update

I've ordered 2 v-band flanges, and have already recieved them from B&G Custom Turbo, great service.

I picked up another stock distributor, and replacing my welded locked distributor. This is the plan that I wrote up from another post:

1. I got another distributor, and bought the weight kit from advance auto parts, it is a MR. Gasket weight kit for $9.00.

2. I got a MSD 6AL BTM box to retard my timming as boost comes in.

The reason that I'm going back to the weight set-up is when I advance my timming up to 36 to 38*, the engine loves it. It'll have throttle responce and hole-shot like you wouldn't believe, but when it warms up and I shut it down, the advance is too much for the car too crank, so I have to back the timming back down. When I get it to where the engine will crank, the throttle responce and out of the hole performance is sluggish.

What I plan on doing is put the loose springs in the distributor, and have the timming ramp in very quickly, say around 2000 rpms. The engine should turn up quickly to 36*at 2000rpms, and when boost comes in, the boost retard box will pull timming 1 to 3* per PSI, depending on where I have the knob adjusted to, which will depend on octane and detonation.

This will allow the engine to crank easily, and ramp my timming up to 36* fast. I'm not going to run a vacume advance at all. I tried that, and couldn't have the timming at 36* during WOT spool-up, because there was about 8* of timming advance taken out when the vacume was lost on the vacume advance diaphram. So if I set it for 36* at idle with vacume, as soon as I got on it, it would drop to 28*, and stayed there, which was fine for WOT under boost, but I lost some performance due to the low timming setting.

And Chevy's love timming!!! The 20* locked that you see on this website is for Fords! Trust me, I drove my 360 ci chevy (350 .060over) with 20* locked timming up the road to a friends house, and when I got there, my headers were glowing red (had fuel trouble too)! It ran like a pig, only building 5psi of boost. We turned the timming up 30*, and 10psi instantly around 3000rpms! Of course I didn't stay in boost but for a second, cause 30* was uncomfortable to me with 10psi on 93 octane even though it is intercooled. I figured 26* will be fine, but we'll see.

IF yall see something wrong or different opinion, lets discuss.


I called MSD, and my 6AL BTM is still in repair, but I can replace my locked distributor, and use the springs to advance it up to 26* and vacume advance it up until I get the BTM. When I get the BTM, take the vacume and plug it, set total up to 36*, and let the BTM pull timming as boost comes in.

I got the cal-tracs on the truck, and have not tried them out yet due to the exhaust leaks, which will be fixed Friday. I have 2 extra rims already, and I have to go get 2 Mickey Thompson drag radials to mount on them, hopefully 325/50/15's will fit. If not, I'll get the 315/60/15's.

I've mounted the gauge in the interior, and made a Manual Boost Controller also, but I'll wait to get the carb dialed in before I start moving the boost.

I think that is all for now. Friday is the day I shall start her back up and take her back out again!

Moss

 

Re: more parts ordered!......(Round 2, skittles)!!!

Just an FYI, the 315/60/15 is the biggest radial they make, tall and wide. So if the 325 does not fit you need to go the other direction.

 

Re: more parts ordered!......(Round 2, skittles)!!!

I have been doing the 35* timing in by 1800 then pull it out under boost to 20* for a while. I think it is the fact that these trucks weigh alot more than a mustang and they need everything that they can to get out of the hole. Mine is still a dog out of the hole but I cant get any more than about 2300 out of my crappy convertor and my turbo doesn't fully hit until 3500. Oh I run vac advance with that as well for good driveability.

 

Re: more parts ordered!......(Round 2, skittles)!!!

dmoss, that engine paint is hilarious!

 

Re: more parts ordered!......(Round 2, skittles)!!!

CW25....

Thats about what I'm going to run this week! I couldn't agree with you more on the weight advantage that yall have on me.

SLOW L8LY....

Thanks! It took a lot of work to design that paint scheme.....

Thanks for the replies yall, I thought this post was getting lost in the corner with the spiders.

Re: more parts ordered!......(Round 2, skittles)!!!

Both the 325/50 and 315/60 have the same tread width of 11". The 325/50 is 28" tall and 13" wide, and the 315/60 is 30" tall and 13.4" wide. This is mounted on a 10" rim, and comes right from their site.

 

Re: more parts ordered!......(Round 2, skittles)!!!

Thanks, I'll edit my last post!

 

Re: more parts ordered!......(Round 2, skittles)!!!

Well, bad news

MSD called today, and they said that my box was "unrepairable". I guess I'll just run a stand alone BTM module with the 6al and 2 step that I already have.

Working on the truck tommorow!

Moss

 

Re: more parts ordered!......(Round 2, skittles)!!!

Everything is up and running, but the carb is kicking my ass, and I have posted in another thread what I have.

For those interested:

I think when I get the carb straightened out, look out!

Re: more parts ordered!......(Round 2, skittles)!!!

More trouble with the carb, but we're tracking it down!

The above thread and this thread is the latest!

Re: more parts ordered!......(Round 2, skittles)!!!

alright,

Got me a bigger carb, and transfered all by blowthrough stuff over to it.

Most of the problems that I'm having is due to timming, and I just ordered a NEW MSD 6AL BTM box from atalantic speed here in South Carolina.

This is the plan for tommorow with my old MSD 6AL.

1. Take and crank the truck up, and rev it up to 2500 rpms using the idle set screw.

2. Set the total timming up to 36*.

3. Idle the truck back down to 900 rpms using the idle set screw

4. Get the timing light, and check the timmiing with the weights in the relaxed position. Write that degree number down.

5. Then take the distributor, and turn it until I get my best vacume at idle. Write that timing degree number down.

6. Then idle the truck back up to 2500 rpms, and check the timming mark. Write that number down.

7. Then turn the distributor until I get the best vacume running at 2500 rpms. Write that number down.

8. Figure out what to do with the distributor to give me the best timming points across the board.

Once I do this, I'll be ready to get the MSD box in Wednesday, and hook it up so it will pull timing out as boost comes in. I'll just have to be carefull if I put it under a load with the timing above, I may have to retard it a couple of degrees in the lower RPM's so offset the extra load.

I think the above should get rid of all the bugs in my timing issues, and make her scream. I'll keep yall posted.

Moss

 

Re: more parts ordered!......(Round 2, skittles)!!!

Man this thing is getting SOOOOOOOOOOOOO close!!!!

Timming issues:

Went through the steps above, and:

1st thing is, my mechanical advance wasn't right. I put the weakest springs on the distributor that the kit had, and they didn't have enough strength in them to pull the timming all the way back to the resting point, so therefore, I was getting about 6* advance from the springs. Very interesting.

So..........I went back to my spring kit, and found the next size springs, and changed ONLY 1 of them. It had the strength to pull it back to the resting point each time I'd manually advance the timming. (rotate the rotor [distributor cap off], and let the rotor go) Crank the truck back up, and got 14* advance from the mechanical advance!

Now, we're running an initial advance of 21*, and a total of 34.

2nd thing that I discovered is that my truck at idle, with no load, likes to idle at 34 to 37* timing. I checked this with the vacume gauge hooked up to my manifold, which I got the best idle at 14". At 22* timing, I got around 11.5 to 12" vacume.

Well, this is where the wheels go to turning and figured that a vacume advance would be ok to use for idling since I'm at least13* from what the motor wanted. So I hooked up the vacume advance, and WHAM! 40* timming. Not good, so I unhooked it and began to brainstorm.

Me and the Dr (friend) got to talking. Of course we couldn't use the vacume advance like it was, cause at part throttle crusing, it would try and advance my timing up to around 53* of timing! (21 initial, + 13 mechanical + 19 vacume) So we put our nuggets together and thought, Hey, it would be cool if we could limit the diaphram movement to around 4* of timing, so we could have a better idle of 26* timing, and a cruise timing of 38, and boost timing of 34 - MSD 1* per pound of boost!

So.......... I found another distributors vacume advance mechinism, and modified it so it would fit on top of the one that I'm using inside the distributor. (cut, grind, too much to describe now, I'll get a pic) Bolted it down, and tried it. First attempt, 21* initial, 26* with vacume at idle, 37* at total with vacume!!!!! Hell yeah.

Needless to say, the distributor hold down bolt is a little tighter.


FUEL ISSUES

I purchased a 50cc accelerator pump KIT, that came with the arm, diaphram, deeper diaphram holder, and pump cams (yellow and brown). I put it on the carb with the yellow pump cam, and off throttle bog is GONE! HISTORY!

Now, I have to do the same with the rear, cause when it opens, it bogs also, so off to the speed shop to get another $50 worth of accelerator parts. After this, I'm pretty sure it'll be some smokey tires OFF THE LINE!

All bullshitting aside, it's really getting better. Now I have to go back to crusing and part throttle shit with the new carb and see if we can dial it in. I know I have to open the PVCR's out, but I'll take it in little steps enroute to the perfect carb.

As far as oil seals on the turbo, I'm pretty sure I cooked them, and I called today to get another H2D on the way!!!!!! We're calling her 'ol smokey right now.

And I ordered a new MSD 6AL BTM, and the UPS man should have it there tommorow, but no playing until the H2D gets here.

I'll keep yall up to date.
