73 C10 big block frame mounts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I used 1/2 ton small block mounts to put a 454 in my 82 K-10.
They will work but the big block fuel pump hits the crossmember.So,I used a shorter fuel pump from a 60's Chevy big block engine.It works but has no return line.
The big block clam shells are about 3/8"+/- higher than the small block shells.
I have the correct pieces but haven't put them in yet.
The big block shells are easy to find in old motorhomes.
Mike.

6.2 diesel clamshells are the same as big block also.
