Nice Frank been watching your build !

 

Thanks Randy..... I have been watching yours too, sorry to see the problems you have been having.....

 

Went today for a short time..... Got the crank drilled for a balancer locating pin using the ATI drill fixture kit..... Then got the balancer installed and marked for the timing tab..... Also put the fittings in the Moroso adaptors, got the oil pressure adaptor in the block and put the cam/crank sensors in place(ARP hardware is coming for these)..... Cleaned up some stuff, this week I will get the heads apart so I can get the ports cleaned up and get the new springs on them.....

Here it is as of now.....

Not much progress this week, I did get the heads disassembled so I can get a little porting done and then they will be reassembled with some new Isky 165A single springs.....

Here the heads are apart.....

And the new k-member got here this week, the control arms are coming.....

Good plan, I fire balled my car at 130+ and discovered how important a well sealed firewall is, I got out ok, but it was pretty sketchy for a second.

 

I also love what you've done with a museum car, looks bad ass.

 

Thanks.....

 

Well not much has bee done for a while, I did something to my back that had me screwed up for about a week..... I have been doing much better for the past week so I went out to the NMRA race at Bradenton yesterday for a little motivation..... Last week I did pick up a replacement intake and exhaust valve and cut the heads down to protect the valve seats when I clean up the chambers in the heads..... Today I went to the shop and started porting the heads..... First thing I did is take the intake rocker bolt bump out of the intake runners on both heads, next I roughed in the intake valve bowl area buy the valve guide on one head..... Then roughed in the rest of the bowl area on one cylinder..... I stopped after a couple hours of work, I really don't want to kill my compressor and it was starting to get pretty warm..... I think I am going to take a little more around the guide but we will see..... Unfortunately it will be a couple weeks before I get back to porting since I will be on a mini vacation next weekend for 3 days.....

I have been collecting some more pieces I will need when I get back to the car..... I got the front lower control arms, Calvert Racing Adjustable Rear Shocks and some trans pieces.....

Here is the some of the porting stuff, a pic of the head casting number and one of the cut down valves in a chamber.....

Here is the what the roughed in port work is looking like so far on the intakes.....

Nice!!! I bought me a bunch of rolls to do the set on my motor as well.

 

are you just gonna use thread sealant on the rocker bolt? or you planning on patching the hole for the bolt with some sort of epoxy? moroso A+B epoxy or jb weld?

 

Thanks, I had to stock up to get these done.....

I will probably just use blue a little blue locktite on the intakes so it can't suck any oil through the threads.....

 

Went to the NMCA opener at Bradenton on the 21st, put the car in the show and watched some racing..... Sunday I went to the shop to work on porting the heads and had a major f-up, I managed to make a hole into the water jacket in the swirl ramp area on the second intake valve pocket(junk 1 new head)..... I have a set of used 862's, I took them apart but they are going to need a lot of machine work(valve job, guide work and surfacing)..... I looked around and found a new complete set of 862's that have never been bolted on, I bought them and got them yesterday..... The only issue with these is you have to be careful what head gasket you use on them because the have the notch in the deck surface..... I researched the head gasket issue today and everywhere I found they say you have to use composite/graphite head gaskets and mls gaskets would leak, but I did find that Victor Reinz is making a new series of mls gaskets that address this issue.....

Here is the hole I made in the swirl ramp area, lesson learned.....

Here is the new heads with the notch in the deck surface.....

Since I have a junk head I decide to see how far I could go in the exhaust port roof before hitting a water passage..... So I ported the exhaust opening to a d shape but not widening it other then clean up..... Then I ground into it until I hit the water passage, it looks like I will have plenty of material there(it was still just over .100 before I hit the water passage after porting)..... Funny thing is I wasn't even concerned about hitting water in the intake side, but was worried about it in the exhaust roof(I was going to use one of the used heads as a guinea pig, but I have the junk head to use instead).....

Here is the ported exhaust opening with the hole ground into the water jacket.....

I am going to take the new heads apart tomorrow so I can get started on them.....

Almost forgot, I got the lifter and trays in the short block yesterday after work..... I also got the 12an crankcase vents made and welded to the new Holley valve covers(I will get some pic's of these tomorrow when I am painting them).....

 

I had a lot of crap to do today but I did manage to get the heads apart..... I picked up a new die grinder this week, my old one was on it's last leg..... I went ahead and tried it on one of the rocker bolt bosses in the intake port, it has a much smoother trigger and produced a much more controlled smoother finish.....

Here is the rocker bolt boss I took down.....

#ad



and I didn't have any time to get the valve covers painted, but here a pick of them.....

Made some progress on the heads today..... Got all the rocker bolt bumps out of the intake runners, then I roughed in the intake bowl area on both heads where I made a hole in the other head..... I roughed both sides of the intake bowl area on one port, I will make some more progress tomorrow.....

Here is where all the intake runners are at this point.....

Here is the one I roughed the entire bowl area.....

Almost forgot, I did get the valve covers painted this week.....

Got a little more done this morning, now I have 6 intake bowl areas like the one in the last picture.....

 

Looks good Frank, any idea what you're going to gain in flow? Just curious how much the rocker bump, and swirl ramp hurt flow.

 

Thanks..... No, I have no base line flow numbers for them and I am not going to spend the money to get them checked..... I know what I am doing is going to help, but without a lot of testing and checking who knows for sure..... You can easily see the differences in the rocker bolt bump and swirl ramps, what you can't see is the bumps and casting flash that is also being removed.....

When I did similar on my 85 Mustang with a boosted 302 it showed quite a bit of difference..... It was a stock 90 GT 5.0 that I had baseline numbers on, after I ported the stock e7 heads and change the cam it picked up over 4 tenths and 4 mph in the 1/8 mile..... Never got it back to the quarter after the changes.....

 

No doubt they'll flow better, just curious if its worth while for us jy engine guys...

 

I worked on the heads some more today, got the intake runners completely roughed in..... Also started to smooth out the intakes......

Here they are roughed in.....

Got the intakes all done, on to the exhaust next weekend.....

Here's what there looking like.....
