73 Cuda exhaust manifold part numbers

[pedlondarite]

Hi all,

New member here.

I recently bought a 73 Cuda 340 4-speed. The car is in great shape but I'll be doing some work over the next year or so to get it as close to factory as I want to take it. I'm going to be asking a lot of questions here!

The first one I have is about exhaust manifold casting numbers. Can you please confirm that 3418621 (LH) and 3418623 (RH) are correct for a 73 340?

Thanks.

Those are for 71-72 340 according to my book. 73 is 3751084 and 3418623 . Looks like the passenger side is the same. Looks like 73 and 74 are the same. This is from the Challenger & Barracuda restoration guide.
