Yes it makes a huge difference. have to keep the heads sealed, should have been an obvious clue if they're putting gaskets in it a lot.

You don't need fancy bolts for under 1200hp. The normal cheap ARP 234-4317 have held down stock heads at 35PSI and 1100+whp.
No I agree 100% with you my point was unless it's realy max effort setup , he would not have to worry about it

The hard thing that some people cant understand.. is that the bigger the engine, cubic inches wise, is it'll run out of turbo really quick. Running into the choke point of the turbo, parts of the compressor map that only make it more prone to detonation.
Personally, racing in a turbo limited class, a smaller engine with decent compression goes a long way. I wouldn't hesitate to hang a turbo or blower on a 12:1 engine (with a 6 bolt setup obviously).
it takes some well researched and good parts to make it fast, and more importantly live. That's what I don't understand about why a lot of these people building the "sloppy" stuff. Spend the money on good parts and make it live longer, instead of cheaping out and having to work on it ALL THE TIME. It gets old in a hurry, just my $0.02

But I agree with an engine that large I'd hang a set of 76/75 or s476's off of it and let it eat.

Well adding the procharger would be way easier than adding a turbo. This is a car id like to be abble to DD should i choose. A/c and all accessories are kept. So NOT race car and wil NEVER be caged. Just weekend toy mostly
