I agree with Milt's comments about quench and the cam design being bigger factors. No offense to the ROP guys, but I really doubt that the thought or execution was very thourough, especially the guy with pinging problems on 93 octane pump gas. For example,at one point he mentions running it

Scott, Have you done any Dynamic Compression Ration calculations for your anticipated engine build? The Dynamic Compression Ratio will tell you effectively how much cylinder pressure you have for the bore, stroke, static compression ratio, and the particular camshaft timing parameters you are

I've found a guy with a set of .040 overbore 350 pistons (used w/5k miles) with a 10cc dish for $65. What happened to the engine? Catastrophic failure? Are the pistons okay for sure? Before you put them in, go over them with a fine tooth comb! Especially the ring lands need to be in spec, or

Scott, You've opened up a can of worms. Only reason I mention it is the guys on ROP say high compression doesn't play well with the computer. I'm not at all sure why. You can see my post and the responses here. http://realoldspower.com/phpBB2/viewtopic.php?p=170732#170732 I am very
