Im going to be building a 408 and need some help with choosing a combustion chamber volume. looking for somewhere around 8.5-9.5
Im looking at the Callies Rotating assemblies with -12 cc pistons. Looking for a set of CNC heads. Just cant figure out what combustion chamber volume to go with. Thanks

Call Richard at WCCH --------------->

 

+1 wcch

 

Broken record anyone? Go with WCCH

 

yet another...... call Rich WCCH

 

Since nobody's mentioned it yet, I recommend calling Richard at WCCH

There are compression ratio calulators all over the net (try a google search). You left out a bunch of variables but assuming zero deck and a 0.051 gasket, you are going to need 75 - 88 cc head to get the range you noted with that piston.

 

i was think maybe he should call richard at WCCH. last i talked to him he was working with a 4"+bore head (edelbrock IIRC) that flowed over 400cfm.
