will this fit a 82 Corvette and any fuel mods needed
Yes this engine will fit your 1982 Corvette. Your Corvette came with the first year for Corvette, Cross-Fire Injection system which is similar to the FiTech Injection system that comes on the ATK Chevy 350 Vortec 350 ci 350hp engine(22582) but not the same. There will need to be modifications to the fuel delivery system and the electrical system.
For more specific detail on this swap you can contact FiTech Injection @ 1-951-340-2624

HP32C 350 will it fit in my Pontiac firebird formula 1989 5speed it has throttle body what modification will I need to do I know that I need to do
The manufacturer has stated that they use 1987-1995 4 bolt main block like GM used in light duty trucks. It will need additional fuel delivery system, different than the stock mechanical pump & fuel lines and should fit the vehicle if it had a 350 in it to start with. This will not work with computer-controlled vehicles.
