You can swap anything from a 350 chevy or a 4.3 V6 to a 351 ford.

check out ultimatecustoms.ca they have a few kits available for 2wd trucks, I'll bet 4x4's aren't much different.

Also a ton of guys on cardomain.com have done V8 swaps, just search years 1987-1993.

I would recommend swapping out your drivetrain however, those axles won't hold up to a V8; at least not for long.

Let me know how it goes.
