E-heads are good but how much more than 308 can a set of street e-heads flow? Me thinks it might not make much of a difference.

Nothing personal, but comparing E-heads to Steel heads with restricted workable passages, plus not having the flow capability to handle the newer better ground cams(and technology) to take advantage of the E-heads better flow capability is redundant. [img]/infopop/emoticons/icon_rolleyes.gif[/img]
I know, a run on sentance, but I had to get my point accross. Never happen. That was then this is now.

boykoman...Very impressive!! Another lesson for the BIG NUMBER lovers. It should be no secret that our Pontiacs make much less HP than most of the turds we drag down the track. Same applies for big CFM numbers. I don't buy into the number crunchers who attempt to apply a mathematical equation using the max CFM of my cylinder heads to project performance levels. On a traditional Pontiac engine, more important factors apply.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
