I have b16 block with 84 bore and 77 stroke, 0.036 head gasket, open combustion chamber to match 84 bore and 9:1 pistons. what is the formular to find Combustion Chamer Volume, Piston Dome displacement? I;m probably in the 8.

I have the web page. As you can tell I change the bore, combustion chamber and pistons compression. I'm interested in finding Combustion Chamer Volume, Piston Dome displacement. So I can plug them in to find out my C/R.

just use the stock combustion chamber volume for whatever head you are running. Unless you get your cumbustion chambers cc'ed this is your best bet. Piston dome displacement should be on the spec sheet that came with your pistons.

If you don't know your numbers, we can't figure it out for you either. That c-speed link works perfect. Just drop in the numbers

I guess I have to find out the formular for myself.

The formula is simple. Cylinder volume at BDC divided by cylinder volume at TDC. It's calculating those volumes that makes the c-speed link awsome USE THE LINK

Got it thanz Earl.
