69 350/350 exhaust manifolds?

[Steve G.]

Hi-
Im trying to research a '69 350/350 motor I have, and all the parts number listings I have are for 53-67. Anybody know what the part number is for the RH (passenger) exhaust manifold on this car? Is it a 2.5 inch dump? There wouldnt be a hole for a choke tube in this, would there? I having a heck of a time figuring out what this number is. Thanks

Last year the 2.5" exhaust manifolds were used in production was 1965.

The NCRS Spec Guide has manifold casting numbers. Both Corvette 350s used the same 2" manifolds in '69.

Thanks Duke. Do you or does anyone else have the 69 spec guide? As I said in my original question, I have the guides through 67. Looking for the RH exhaust #.

Wayne has it; GM casting #3832481 is the one. This manifold was produced both with and without AIR fittings. ALL 1968-69 small blocks use this manifold WITH AIR fittings for the right side. The left side is GM #3872765. ALL of these manifolds have AIR fittings.

No small block Corvette after 1965 used 2-1/2" outlet exhaust manifolds; ALL were 2".
