Summit Cam Recommendation

Either one is fine. I put 302 heads (65cc) on a 67 318, .050 in the hole pistons, 6900 cam and it runs great.

'67 318 has advertised 9.2:1 comp versus the 8.x of the 1970- mid 80's 318.

Those 302 heads were probably also off of a 9.2:1 mid 80's- '91 318.

Did you measure/calculate your actual ratio?

Very curious.

Also curious about how it affected MPG.
