69 350 exhaust manifold

[Jim M.]

My 69 Corvette 350/350, recently purchased, came with headers and what appears to be a home made bracket for the alternator. I would like to put the stock type manifolds back on the car however I'm really confused by the choices. One of the major suppliers has a manifold for the right side but it appears as though the left side is listed as a 70 to 72 model. I also noticed on some othe sights that the forward end on this sides manifold has either a squared off casting or some have a pointed looking end piece, both I'm assuming for an alternator bracket of some sort. Since I don't have the proper bracket for the alternator and haven't found any pictures of this setup, I'm pretty much at a loss as to what I should be buying. Any help or pic's would be appreciated.

The left (driver) side manifold should be a GM casting #3872765. All versions of this manifold have AIR fittings which are required for all 1969 Corvettes.

The right (passenger) side manifold should be a GM casting #3932481 with AIR fittings (not all 3932481 ever made had AIR fittings but all those used for 1969 Corvettes did).

The alternator bracket you need is available in reproduction.

Jim,
I can sell you the correct NOS bracket (GM #3846565) and a very good original alternator brace (GM # 3884640) for less than the reproductions. The "repro brace" is nothing more than a 63-64 Chevrolet 409 brace (GM # 3826928) which you must modify to make it work. It doesn't even look the the original brace. Let me know if you need some help. I have dozens of original Chev. & Corvette alternator/generator braces and dozens of original brackets in my 30 year collection of parts. You can have my 409 Chev. brace (GM #3826928) for free if you want, just pay for shipping, but I don't think you really want it.

just a question here because of crs or otherwise but didn't the low horse power 350 cars lack A.I.R ? did they still use the drilled manifolds with plugs Steve

ALL 1969 Corvette engines were originally equiped with the AIR system.
