So I just dropped off my Olds 350 powered 1977 Firebird to get new exhaust from the manifolds back. The muffler shop discovered that there's small cracks in the exhaust manifolds. They said they could repair them but that's kind of a half assed solution. They recommended I score some replacements. I'd appreciate any links and resources for replacing these suckers. Ah Murphy's Law!

Or if you want used manifolds please post the casting numbers. 350 manifolds are pretty common and reasonably cheap. I'm guessing the large casting number for the drivers side will be #1 and the passengers side #5. John

 

I called the shop and the dude could only see the numbers on the passengers side:

417754

13057

B2Y

If those aren't the right numbers, please tell me where to look.

Thanks!

Hi Brian
Yes, that would be the #5 on the pass side. The drivers side would be 380001.If you want used manifolds create a parts wanted thread. I've got some up in Medford Oregon but you can likely find some closer and save on shipping. John
