Compression Calculator

Thanks, Blu. Using the 7.3cc on the Wallace Calculator is still came out to 9.7 so overall its really close to yours. You are using a .039 head gasket where mine is .050, which is what Edelbrock recommends with the 63cc heads. I think this gets me close. I'll give Ken a call back and see if what he recommended for a cam still is a go.

What cam do you have @72bluNblu?

Yeah it's not a crazy difference, only a few tenths anyway between the published and the info I got from the tech. I built that engine for my Challenger like 12 years ago now, I couldn't even tell you how I decided I wasn't getting the right numbers with them being so close. It ended up in my Duster because I bought it before I tore down my Challenger for rust repair.

The cam is a Lunati 60404, I think the new number is 10200704.
