i want to know what happens when you put a flat top .172 down in the hole with boost.
SBF 351w 9.5 deck
3.5 stroke crank that dictates a 6.200+ rod
canfield 195 head 54cc chamber
4.100 x .047 gasket
93 octane and water injection for a safety net
intercooled EFI
69mm turbo
all the boost it will handle to make 800hp. turbo will be out of steam if it can make 800 at the crank.

I found a cheap wiseco 4032 flat top for a 383 SBC with a 1.425 C/H, @ .172 down i would have 8.7:1 CR... any ideas if it would be detonation prone like most people figure?

My opinion is that with a boosted application quench isn't really isn't a issue. That is also what I have heard from other people who work with boosted applications.
