Well the right side is the same as any '67-'69 383 A-body 2863900. The left side for 440 is 3462017. The M-codes used a spacer on the right side between the exhaust manifold and the head pipe which brought both sides down to where the 383 exhaust would be in height. Therefore the standard 383 head pipes were used on the 440 M-codes.

I have some spacers made, but hopefully will be having more made.


I'm the CARETAKER of Weinstats '69 440 'cuda registry and have 104 of the 360 cars to date. 84 fastbacks/20 coupes. Always looking for new(REAL M-code) '69 440 'cudas to add to the registry so drop me a note if any are found or known. This isn't a publicly released registry. Thanks, Dave
