Cylinder Head Porting and Power Production

My buddies 350 Pontiac Stocker has gone 10’s @3300lbs with heads that flow 200 @.420 lift(max lift).

With the stock intake and carb....... it’s over 2.06hp/ci.
I guess those Pontiac engineers knew what they were doing......30* seats and all.:usflag:

I never really look at hp/cfm, but it appears both his 350 and 400 stocker motors make the same hp/cfm.

The 350 is slightly better in the hp/ci dept though.

And let me guess with a QJet.
