I bought a '63 c10 Fleetside in good shape. It has the 250/6 in it now that runs good except rear main seal is bad. When oil pressure is up it runs good.
Swapping in 80-85 350 with a sm465. Got both engine/tranny/entire '73 front end for $425..so I thought it was a good deal. Question is how much cutting will I need to do to the low hump cab to install? If anyone has pics that would be awesome also. I will be selling the 6 when its all done in case anyone is interested. Thanks for any help you can give...
