i want to calculate the theoretical compression ratio with the new aluminum heads but I don’t know the piston dome volume. I have the cast 10:1 pistons from TA, but their site doesn’t seem to list the specs for these pistons for a 350 bored .030. Anyone know?
If its the 340p cast pistons, i used an estimated 10.5 cc Roughly 9.7 with untouched deck, felpro gasket.
Do you know your deck height? Or how deep the pistons sit in the hole? Typically the 10:1 pistons give about 9.5:1
Thank you for the help. My deck is .034” I am using the Felpro head gaskets.... .040” thick? Using +10.5 cc on the piston volume, .040 on head gasket 55.5 cc head volume on aluminum heads 3.83” piston diameter 3.85 stroke .034” deck height Calculates to a 10.08:1 ratio at the below listed site: https://speedmaster79.com/tools/engine-compression-ratio/
