It will drop right in and not a thing to do..
What make is the engine in it? If it is a Chevy 327 engine then the 350 will bolt right in. If it is a Pontiac 326 engine you will need to either swap transmissions to a Chevy pattern or buy an adapter plate.
There's no such thing as a Pontiac 327. Either somebody has already swapped it to a Shove-a-lot 327, or its a Pontiac 326. If its a chebby engine, then they already swapped transmissions and the shove-a-lot 350 will drop in. If its a Pontiac 326, then you'll have to find a transmission with a Chebby bolt pattern, and re-route things like the starter wiring, AC plumbing (if so equipped) get the Chevy-style brackets for alternator, PS, etc.
