more than likely not. although pontic was apart of GM until recently. back in the 60s and 70s pontiac had no afiliation with GM. that is why there were two diffrent bell housings for TH350 and TH400 transmittions. one for chevy and the other BOP or Buck, Olds, and Pontiac


No. You can find headers from Doug's for around $400, sometime less. But headers on a 67 GTO will hang down below the bellhousing, will interfere with the starter, and are a royal pain to bolt onto the driver's side. A better option is to pick up the aftermarket Ram Air 3 cast iron manifolds. Cost is about the same. They have almost equal HP gain as headers, bolt on perfectly, don't overheat the starter, and look great. Try Ebay. Intake and valve covers from a Chevy will not fit.

chevy headers cannot fit a pontiac engine totally different angle head flange, chevys bolt up on the side of the head ,pontiac on the bottom, not even close.exhaust ports are different also. sell your chevy stuff & buy pontiac its about the only way , 2 totally different engines. try Summitracing.com or jeggs.com they have everything you need!!
