1967 GT500 Exhaust Manifold
« on: February 12, 2020, 02:15:50 PM »
I can't find a part number in the Shelby Registry for a GT500 exhaust manifold. Is there one number for all? Are there different numbers for early cars versus late cars? Thanks.

Also, is there an exhaust manifold supplier or part that is recommended by the experts?

Same exhaust manifold as the 67 390 so there should be a fairly decent supply out there (until you need one of course :)  Of course condition (rust pitting) and date code can eliminate and reduce the options. Passenger and driver side have different engineering number (number case into the manifold itself)


Only available used so check with those that part out cars, hoard parts or sell parts online

I have two sets of 390GT / 428 Shelby exhaust manifolds with various date codes that are about to go to eBay unless one is right for you. Sorry I don't have the thermostat valve for the RH side. I do have a spacer for the RH side.
