305 to 350 swap

I have a 1988 camaro iroc z with a blown up 305, i recently bought a 1995 buick roadmaster with a 350. Would it fit and what would it require to do the swap?

Bolt in deal bolts have a one piece rear main seal and same intake pattern. If it’s efi you need the memcal or prom reprogrammed and larger injectors.

Isn't one a TPI engine and other is reverse cooled LT1 derivative?

Physically would fit, but wiring, etc will be much different.
