Compression Ratio Calculation
I am trying to figure my exact CR. I have a 383 (400 crank with 3.75 stroke and 4.03 bore) with 64 cc heads, flat top claimer pistions with 6 inch rods,
stock head gasket. I am guessing around 12-1. I am looking for something more exact if someone can help me out.

Re: Compression Ratio Calculation (Blake-73)
it is close to 10:1, but can't be exact, without a teardown. Even then, you would have to check with bill clinton to see what the definition of "exact" is :lol:
