Dynamic Compression Ratio

d that if the intake valve isn't open when the piston is on the intake stroke it effectivley is reducing your compression ratio. Ow... Teacher, my brain is full, may I be executed...er...I mean excused? With a bunch of estimates, with my 22cc dish pistons and my not-so-radical cam puts my

Hello all- But...it seems that there's no "in between" my 22cc dish aftermarket pistons and flat-tops. Yes there is - the TRW/Sealed Power/Speed Pro L2321F forged 5.8 cc dish pistons. These are the replacements for the "10.25:1 compression ratio" engines. Summit car

Hello all- Man...I'm kinda getting disgruntled over this whole compression thing. I paid $150 for a set of 7a heads, thinking they'd get me into the 8.8:1 range (per the FAQ)... Now...with the added piston-to-deck clearance, the added thickness of an aftermarket head gasket, plus aftermarket p

k height is the distance from the crank centerline to the flat head surface of the block. By knowing this, the rod center-to-center length (rebuild the rods to equalize this), the combustion chamber CCs, and the exact stroke length, one can design any type of piston they want for any compression

Hello all- You will need the deck height, Scott. Why don't you go here http://www.csgnetwork.com/compcalc.html Doh! I should have remembered that there are neat little devices like this. My old cutlass, I built the same engine than you describe and ended up with a measured 8.9:1, perfect fo

You will need the deck height, Scott. Why don't you go here http://www.csgnetwork.com/compcalc.html And vary the deck height. Ultimately you will have to measure. CC the heads and cc the combustion chamber at TDC. My old cutlass, I built the same engine than you describe and ended up with a

Hello all- Asking for the help of number crunchers out there. 350, bored .030. Aftermarket pistons w/22cc dish. Aftermarket head gaskets (.040?), 7a heads w/64 or 67cc combustion chamber. I'm not sure of the deck height. Can someone out there give me a clue where I'll be at? Thanks! Scott
