Darby. I acquired the same P4B that you did and hogged it out to accommodate a Spreadbore. I have not run mine but how did yous work out?

The original Edelbrock P4B was patterned after the 1960-61 Pontiac 389SD 1x4 intake with some accomodation for street use (heat crossover, choke, etc.). It was a pretty good manifold for the time if you ran an AFB or Holley carb. If you had 1967+ heads and a QJet, you were better off with the 1967+ Pontiac cast iron intake.
Here's a picture of the 389SD 1x4 intake:

Decent for a stock replacement type manifold if the later 67 & up. Performance wise there are a lot better units out there. If using an HEI check for clearance.

I got decent results with one.
Took a #17 headed 350, changed the 2 barrel intake to the P4B, added a Holley, a set of headers and dual exhaust. Nothing fancy, just a good street tune. Backed by a 4 speed it was a pretty responsive street engine. Probably better performing intakes around no doubt, but IMO, a blasted and cleaned P4B looks better than some other intakes. For a cheap and simple 2 to 4 barrel swap on a 350 or 400 I'd recommend one.

I wish the factory would have kept that long manifold bolt set runner 8 as it does not choke down the port area as in the latter manifolds!

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.
