Thread: Building a 396 -- Pistons??

Tweet

Thanks for your reply Pat!
I do have another question or two...I'm fairly new to big blocks (I've built lots of small blocks) so i don't know much about these heads. I do know they are 113cc, open chamber, and oval port. Are they any good? Also I'm running an Edelbrock Performer 2.0 intake and cam. Is there anything else I should be doing to this motor to put out 400+hp other than changing the pistons? Is changing the pistons necessary or is there something else I should be doing instead. Like I said I'm running about 8.5:1 compression now. This car (1967 Camaro Convertible) is only driven in the summer months, on nice days. How high of compression can I run on pump gas (92 octane) Again, I appreciate any advice.
