Thanks Pops. I should have specified Big Block but thanks. The TTI link lists some but its not specific and I'm not sure it's correct on all accounts

I did some searching the for sale ads and picked up some info. Can someone validate?

72 Big Block:

Left side cast # 3671595-2
Right side cast # 2899879

73 Big Block:

Left side is 3751068-2D
Right side # 3751071.

Are the 74 the same as 73 on both sides, one or neither ??

I don't know much about the BB cast iron exhaust manifolds, especially in 73-74, I always run headers usually anyway, a nice 10%-15% HP improvement...LOL... IIRC Year One had manifold casting #s listed by years, or use to anyway, if that helps, there site has changed allot thou I'm not sure if you can even find them any longer... Maybe you could contact Accurate Exhaust Products LTD. they are Mopar Exhaust experts... sorry no #'s

Thanks Budnicks. I found above numbers in for sale threads here on FBBO so I feel pretty confident about those but don't know what was used on 74.
