I just finished my 383 with 5.7 rods, keith black flat top pistons and AFR 195 heads (dunno cc's) anybody know where my compression ratio should be?

 

if you tell me the CCs on your head,what type of gasket did you use,and if you had your block decked i can figuer out what it is. if you have 64 cc chambers, stantard gasket and a lil bit taken off the deck you will have 10.6:1, if you give me some detales i will tell you.

350,performer RPM intake ,650dp, 700r4, headers, 3inch exhast

 

76CC heads

 

Here's an on-line calculator. Have fun.

I hope its not injected...

 

Mike, why do you say you hope it's not injected?

 

Cuz the AFR 195's wont work with a stock tune port base manifold. The intake runners have more opening tward the top.

 

What is the piston compression height(in inches) and the piston volume (in cc's)? What is your block deck height and what gasket are you going to use?
I have a spreadsheet in Excel that will give me the exact CR.
