[QUOTE="exdeath, post: 5360410, member: 56343"] It's the sum of the piston top to block deck height + the compressed head gasket thickness. The closer the top of the piston can get to the head at is circumference the better. The 'squishing' that occurs at the cylinder edges causes turbulence that violently squishes (hence also squish band) the air into the center of the combustion chamber and the swirling action 'quenches' or cools the combustion chamber by preventing static hot spots, hence being able to run higher compression / boost without fear of detonation. The tighter you can get this the better, ideally you'd want .000" with the piston barely touching the head at TDC but you have to allow a little for potential carbon deposits, rod stretch, metal expansion, etc. Turbo on a stock block can make 850 RWHP on pump gas safely, as far as the tune and detonation is concerned, soley judging by the number of stock block turbo cars we've seen now. At that point its prolonged pulls and heat soaking of the cylinders and tight piston-cylinder wall clearance that would kill the stock block over time. So figure with a stroker (more cubes) with looser piston cylinder clearance (no heat/expansion problems and rev to 8,000), and good quench (more compression/boost and less timing), then throw some fully worked over heads and a set of cams on top of it, I'd say yeah, 1000 RWHP daily driven pump gas Cobras wouldn't be far fetched. At least as far as the engine is concerned... Just nobody has been willing to spend the cash it would take since you can already make these cars own with pocket change. As for me, I'm tired of spending money upgrading my PC every 6 months to play games that suck at max settings... only for the PC to be worth 1/20th of what I paid for it 3 months later. So I'm willing to make this my full time hobby and divert the cash flow. [/QUOTE]
