1982 Pontiac Trans Am Engine Swap?

[Satchel]

Looking for an engine swap, what would be the best option for something that requires minimum or no mods/work to swap the stock engine to a 500hp[ + engine?

Or something close like 450 engine..

Thanks in advance mates anything is appreicated.

Put in a big block Chevy or a Pontiac 455 that has been overbored. Money will be your only obstacle.
