How much cylinder head flow needed to feed 535CI?
This is going to be very vague I know but approximately/roughly how much cylinder CFM flow would be required to feed a naturally aspirated 535 CI Pontiac bracket engine? I'm pretty confident my 290cfm heads will fall well short.
Assumed Variables: my 78 Trans Am below, Northwind 4500 intake, necessary size Dominator, appropriate size solid roller cam. E-85 fuel
Playing on the KRE website, it looks like I can have my KRE 290 D-port heads and Northwind opened up to 340cfm. Of course I'd probably have to find some round port adapters so I could run bigger round port headers.
Thanks,
John
