1990 6.2 Diesel to 350, or LS1,?

I have a chance to get a pretty decent shape 1990 Chevy Cheyenne 6.2 Diesel 4x4 ECSB for $500, the thing is the 6.2 is dead. So since I already got a truck with a 6.2 I want something different, something with a gas engine, I was thinking about getting a Chevy 350 or maybe an LS1, how hard would it be to convert it to a gasser? What parts would I need to convert to a gasser? and any other tips you guys can think of. Thanks

I'd check it over good. A 90 model 4x4 diesel is probably completely worn out, drivetrain and all. You'll need engine, trans, transfer case and probably front diff. They just didn't build them very well back then IMO.
