1978 400 cam upgrade?
Ok, maybe a stupid question and there may be many threads about this from before..... but, in my 78 Trans Am I have the Pontiac 400 (l78 not w72) - but with 6x4 heads, edelbrock performer intake, edlebrock 750 carburettor, long tube headers and 2.5" Pypes dual exhaust. Th 350 auto and 3.23 rear end. Otherwise stock. Now I'm wondering if I have anything to gain from upgrading the camshaft? And recommendations for this?

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.
