Rear dump manifolds in 67-72 trucks. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Will it work? I was wondering if rear dump manifolds from a '73 chevy truck would work on a v8 in my 70 c-10 (2x4). Is anyone running these?
Thanx in advance.

They did not work for a '73 454 in a '71 with manual transmission.

Thanx for the info on the big block manifolds. I thought all stock big block manifolds where the same no matter what year or type of transmission.

I was wondering if the rear dumps on a sb 350 V8 with auto trans (th-350) will work in our trucks.

This is a 1970 truck with rear dumps. It has the 1970 BB towers. Dont think they will work with SB towers.
