I'm picking up a set of exhaust manifolds that are being sold from a a 69 cutlass 350.

The passenger side looks like it has a large #4 stamped on the front runner along with a heat shield cover.

The drivers side has a #1 stamped on it with a black lever near the outlet. No center dividers either. Number on the drivers side are GWY 650001LH and D6 129.


Any help would be appreciated.


Thanks

 

I have seen 350 manifolds fitted to 455,s before with a little work and yours sound like the pair i saw mounted. by the way after a little massaging these manifolds only cranked out 15 net less then doug thorley headers 1 and 3 qters. or 22 to 23 at the flywheel. think about it with a little work and hogging. by the way open exhaust about the same as headers corked up and cheaper. nice winter project.

 

Manny resize your images and they should upload OK or host them at a site like photobucket and then link to them in your post

OK, so your wanting to put these on a 455, correct? They will physically bolt up but the area inside the manifolds are significantly smaller on the small block vs. the big block. Here's a picture to compare/contrast them. The one with an X is the drivers side of a 1971 Olds 98 manifold. The number 1 is the drivers side of a 350 manifold like you've got.

I don't know where putting them on a 455 came from??? I'm buying these for a few bucks to put on my 72 350 olds. I was just wondering who could identify them for me.

 

Sorry... they're late 1960's early 1970's manifolds. Should fit your 1972 just fine.

The exhaust manifolds are for sale for $25 bucks. They already have the crossover blocked to run a dual exhaust. They are in Springfield MA. PM me if u want the sellers contact.
