Here is one for the Pontiac guys. This intake off a 56 Pontiac. My question is will it work on a 1960 Pontiac? It looks like it would but I don’t have the 60 V8 in front of me and I know that year is a little different. Sent from my iPhone using The H.A.M.B. mobile app
This intake uses a smaller carb & does not have the timing cover water bypass. Still a $125+ intake though
I believe 1961 was the year they made significant changes to the water passages in the heads at the intake manifold. My ‘60 Pontiac and the ‘60 Pontiac 389 we put in our boat didn’t have the bypass hose in the front of the manifold. That came later. I believe the intake manifolds fit ‘55-‘60, then ‘61-‘64, ‘65-up. The ports and passages are smaller in ‘55-56 manifold but it should fit ok. Sent from my iPhone using The H.A.M.B. mobile app
Here is a picture of the 60. It is hard to tell but I don’t see a water passage for the timing cover. Sent from my iPhone using The H.A.M.B. mobile app
It will physically bolt up. The 56 uses a Rochester small base 4 barrel carb while the 60 uses a Carter AFB carb. Not sure if port sizes are the same but if the 56 has smaller ports you'll need a 56 intake gasket set.
Unless you’re getting the ‘56 manifold for a smokin good price I would hold out for a later manifold or even an old Edelbrock P4b. Sent from my iPhone using The H.A.M.B. mobile app
I’ve had the 56 intake for years. I originally bought it for a 55 Pontiac I had but the car is long gone. Sent from my iPhone using The H.A.M.B. mobile app
The manifold should bolt up to the cylinder heads. Unsure about generator brackets, A.C. brackets, etc. As Rocky mentioned, the 1956 used either the Rochester 4-G or the Carter WCFB 4-barrel. While the carburetor bolt pattern is the same on the 1956 as the Carter AFB used in 1960, the secondary throttle size in the AFB are larger. At best, there would be a restriction of airflow on the secondary side. At worst, the secondary throttle plates might hit the intake manifold. Would suggest looking for a 1960 cast iron Pontiac intake. The aftermarket aluminum manifolds for this period Pontiac will lose you both weight AND power. Since virtually all Pontiac enthusiasts believe the legend of tripower, finding a genuine Pontiac 4-barrel intake should be relatively easy, and inexpensive. Jon.
Good to know! Does the aftermarket intake not flow as well as the factory cast iron ones? Sent from my iPhone using The H.A.M.B. mobile app
