Vannin' Home Forums Chevy General Discussion Headers

Hi I was wondering if anyone knows if headers from a 87 firebird will fit my 77 GMC any help would be appreciated thanks

While I can't say 100%, I can tell you that while I had my engine out I marveled at how close to the same shape the set of 3rd gen F Body shorties I have were to the stock van
manifolds. If I hadn't had a complete exhaust system to use I would have tried them. They weren't going to bolt up to the Y pipe without modifications.

SECOND GEN FIT MY 77 DONT KNOW ABOUT THIRD IF YOU ARE ALREADY APART CANT HURT TRYING THEM

Thanks for the replies I haven't bought any yet but think cam going in my 305 so think I'm going to put 350 in and figure good time to put headers on so just keeping eye out for motor and headers have all winter to find
