I need the compression height on a stock NA piston . I need this to calculate compression height on new stroker pistons. Also if someone has combustion chamber volume on a stock NA 8v head that would also help. Thanks

V2Rocket

should be 40mm.
chamber is ~56 cc IIRC?

Thanks V2Rocket .Do you know the deck height on a 2.5 block its a 1988 NA block . Or could someone point me in the correct direction to find the number.

V2Rocket

230mm/9.055"
And actually the compression height should be a hair over 40mm

Deck is 230mm, rod is 150mm. Stroke is 78.9mm, 230-150-(78.9/2) =40.55mm if the pistons run flush to the deck.
