Gen IV to SM465 in a K5

[Oilbrnr]

So I'm the second owner of my '77 K5. The original owner put a Goodwrench 350 in it back in '91 and it now has ~40k documented miles on that motor. In his later years, he didn't drive the truck much, and the last two or three years it just sat. (he went into a retirement home). Valve stem seals are leaking bad, clutch chatters some, TO bearing just started to whine, and the original Quadrajet needs shaft bushings, etc. In other words, the time has come to do something!

I have a 2007 4.8L that I would like to swap in. I'm keeping the SM465/NP205 for my own personal reasons. A tranny swap is not an option.

Is Advance Adapters the only source for a flywheel/PP kit as far as anyone is aware of?
