compression ratio

[440dodgeram]

i put a 78 440 in my 88 ram and am a little dissapointed the engine is rebuilt as the 78 2 years ago i want to hop this engine up and need some sugestions,

first the manual says the motor has 8.2 compression ratio and a small 4.25 lift cam, and a cast crank and new pistons (bored .040), i think the heads are 88cc

edelbrock has the aluminum performer heads in 84cc, does anyone know what this will do to my compression ratio, i want to put a 4.80 lift cam in it but the compression ratio right now wont let me

if i can get a good head and cam package and have my motor hold up for about 3years i want to eventually tear it back down and put the 496 stroker kit in it and re use the heads and cam if i get new ones

I get about a .5 point increase in your compression ratio when adding 0.040 to the bore and subtracting 4cc away from the chamber

Also - I had to goto 22cc dish pistons to get your original compression ratio.

I may be missing something - you may want to try and put more exact numbers in for the gasket+deck and head gasket thickness
