Ok i know there's no such thing as a compression calculator, but im sure someone knows a ballpark figure, im running a 97 coupe, with a Y7, im going to be running p29 pistons, OEM MLS head gasket, intake, header, king rod bearings and ACL mains, i know none of this matters, but i just figured i'd let you all know what im doing. Anyone have a clue of what type of compressions numbers i should see?

 

nothing lol
