'67 shortbed tranny question

[Jsoden]

Hey guys, I've got a 67 shortbed c10 that had a standard 3 speed in it when I got it. I dropped it off the the transmission shop to have a 700r4 installed that was given to me. Three weeks and $900 later the mechanic tells me that he installed the transmission but it wasn't any good. It'll shift and drive but has no take-off power and kills it if you stop in gear.

Long story short I'm about to have a known good 350 tranny out of my 78 suburban. Can anyone tell me if that's going to be a bolt up swap, or am I going to have to swap out the drive shaft again? (700r4 was out of an 82 firebird if that helps)

Thanks for any and all info.
