Re: What does "compression height" mean?
Thanks guys, that's what I though and what I was looking for. I DID measure to the top of the piston as it relates to the deck of the block and NOT to the top of the dome, exactly as Tom's drawing shows.
I was almost sure that the advertised compression height was to center of wristpin, nothing else would be logical, but couldn't make the numbers work on a pair of pistons I saw advertised with any stroke combo I could come up with and any rod that was listed in Summit or on E Bay in either a 9.8 or a 10.2 deck height block.
Since it's clear now I guess I'll go back through my math and see if I made a mistake. I tried plugging in 2", 2.1875" and 2.25 strokes with 3 commonly listed rod lengths and it wouldn't work last night unless I made a mistake with the math.
