No matter where I look. I cannot find a set of headers, or a set of manifolds for my 403 olds they are insanely priced. so I'm looking here. If anyone got a pair they'd be willing to sell hit me up.

I should have what you need. What is the engine in? I'm guessing a T/A. Please let me know. Thanks, Bob.

In case nothing else comes up that is workable, there is a guy selling a pair of 403 manifolds for a 77-79 T/A on craigslist Los Angeles for $100. Listed under auto parts for sale. Don't know if he is willing to ship, but you could ask.

Will a set of manifolds from a 72 cutlass with a 350 work. I looked on Facebook mp and I can get a set a couple hours away from me.

Thanks for any insight Andrew!

That question is impossible to answer without knowing what car you are installing them on.

Try the olds site. www.classicoldsmobile.com.

I deal with this when customers contact me at Pypes Exhaust. The thing to do is contact Thornton Muscle Car - https://www.thorntonmusclecars.com/ They have a manifold called the 350 Jr which will bolt right up to your 403 engine and then you can use the Pypes downpipes DOF10S.

Okay I'll add some more detail it's for 77 lemans with the 350/403 olds. For the high altitude emission regulations, but since wy doesn't have those anymore. Anyone use a set of block hugger shorty headers? Or is there any header sets. I just never realized how dumb those manifolds were. Even for duel exhaust.

Isn't it crazy the things we take for granted. Who would of thought that a
set of manifolds would be so hard to find. are we getting old, I know our
cars are. Who would of ever thought?

I have almost every exhaust manifold that Olds ever produced. I sent pictures and explanations to the op of what would work for him, including factory exhaust manifolds for a dual exhaust set-up. I don't believe that he understands the concept.
