This is a common swap but nothing from the original 6 cyl will work on the V-8. I have done several of them using the original trans. If you send me an email at [email protected] I can send you a spreadsheet listing the parts you need for the swap. Fred

That is great info. I have a '59 GMC 3/4 ton with a 270 I6. The motor is shot. I would like to replace it with a late model, ('72) 250 I6 or a generic 350 but keep the stock trans. Is your offer still open on a list of parts needed?
Many thanks,
