Hello gentlemen, I am new to the site and I have a few questions. I need to know if it is possible to swap out the old knocking 305 v6 for a 400 sbc with semi ease and what are the part numbers or specs on the front wheel bearings. It is a 1966 GMC 4000 and it is 2x4. 4 speed 2 speed rear with a 305 v6 that knocks like a hammer.
