260 to 350 engine swap 80 cutlass supreme

Would like to find a good running 350 or 400 for my 1980 olds cutlass. Anyone know where to find one? Also will the stock 260 tranny bolt up to an olds 350?

The swap to an olds 350 a bolt in job. Yeah, the trans will bolt up. If its a th200, it won't last long behind a 350 engine.
Best bet is finding a 350 or 403 with a th350 trans already bolted up. I see them on craig's like that.
