What 4 barrel manifold will fit a 326 block
 

Would like to put a four barrel on a 1967 tempest 326 Pontiac what original Pontiac manifold will allow me to do that. thank you

I think any Pontiac intake from 1965 through 1971 should bolt on.

Pontiac had a 4 bbl intake for carter afb carbs(basically a square bore intake all bores same size)and one for a Rochester quadrajet (rear bores are large).

All 1965 and 1966 and some 1967 Pontiac V8's used AFB manifolds and all will fit your 326. In 1967 some used Quadajet carbs and all 1968 through 1971 Pontiac V8's used them. Those manifolds also will fit your 326. Try to get manifold and carb because there are differences between the carbs and it is always easier to use the correct carb.

Thanks
 

Thanks to all!
