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.
