I have the summit Pro LS turbo cam. It’s basically a copy of the BTR stage 2 turbo cam. Not identical but very similar. Porting stock castings is...
Yeah, I haven't been here in a while. It has gone through quite a few changes. Added and A2W intercooler and picked up a bunch. Broke the 3.42...
I plan to. Actually mine is already built and runs well. All I am doing is sharing some personal experience with these engines, not what I read on...
I'm not against softening the chambers. I believe OP's goal is a little strong for a 5.3 on pump gas no matter which OE head. I hope you are not...
And I am pointing out that the difference is negligible. With a mass produced non performance cylinder head, you might get 5cfm difference from...

243 and 317 have the same port and valve sizes. Only difference is chamber size.
This. Iirc the 3.8 series II was an optional engine in those cars. Those respond well to boost.
I see what you are getting at. I will message Richard and see if he wants to get a bit more out into left field. If you guys do not recognize him...
I have given this a bit more thought and in a way you are right. Because if the turbo setup is well thought out and properly sized you can have a...
Be just as well off with a carb in that case. I vote you unload it all and go Holley EFI.
I have used REALLY nice CSU blow thru carbs and Holley EFI. While they both work, and make power, at the end of the day the carb is still just a...
Most small block Chevy like at least 34° total. I would bump the timing up a little first and see if that helps.
How much compression and what fuel? Timing sounds WAY too low to me. Like around 10° too low depending on those two factors.
No one is saying it will be optimal. I'm just saying it will still run, and make power if everything else is right. But I see folks blaming the...
