Sorry, meant chambers. 64cc is too small for pump gas with flattops on a 400sb. (11.7:1 with .039" quench)

Have you bought the pistons yet? Wiseco makes a 13cc reverse dome piston that comes in at 10.7:1 with a 64cc head (Part No. PT 096H3). That's more suited for your cam.

yes i have bought them and i just went and picked it up i will not be running pump gas racing fuel only not an everyday driver track only

In that case, you'll be fine. You have enough compression to run a bigger cam if you wanted more power.

I have a lunati cam .645/640 lift roller soild lift cam that im going to use when i get my afr heads out the shop. With this cam it will bleed off all the compression off the motor and with the afr heads i want have a nuff compression for the .645/.640 roller cam. Im stuck and dont know what to do.I had this cam in my 383 but i droped a valve with afr heads in the 383 stroker.

That's good lift but what are the rest of the specs. Advertised duration and @ .050" duration, lobe separation, and installed centerline?

What is the chamber cc's of the AFR heads?

the cam is 276/284 at @.50 lobe separation is 106 and 110. And the heads are 210cc/66 i thank the valves are 2.08/1.60

It was a simple question.
I guess it must of been to difficult a question for you to answer.
It is your story.
