Re: Next steps for the 63?

If your going to rebuild engine 350 cheaper to rebuild then a 6 cylinder
Find a 14 bolt diff out of a 73 up truck
You must have a dana 60 as eaton diff are 4.10 and numerically up

Ls engines are nice too though research them first

My 62 k20 getting a l31 vortec 350 runs great needs new intake seals best price it was free the guy was determined he blew the head gaskets I fired it up drove into the garage good oil pressure pop the hood see antifreeze leaking out of the intake

I would look for nv4500 for a tranny 3/4 needs a tough tranny at the very least nv3500
