building frankenstiens. swaps.

hey guys couple of questions. my dad totaled his 99 gmc sierra 2500 w/ a 5.7 and i was wondering if my 91 sierra 1500 w/ a 4.3 can handle it. its a manual. also if the rear end can do ok with it too. thinkin bout stealin his motor. also if the front end(bumper, fenders, grille, hood, radiator supports, etc...) off the 99 will fit on a 94 chevy 1500. i did some searchin(not alot) and came up empty. thanks.

Yes, Maybe, and yes. The motor & trans in your truck will have no trouble at all. Which rear is in your truck now? The 8.5inch 10-bolt? If so, thats will do just fine.

As for your body parts, its a maybe. MOST of the GMT-400 truck body parts are interchangeable but I know a few are not. Just cant remember specifically which one(s).

thanks. its the 10 bolt. i might be leavin the 4.3 in there for a little while longer. my plans are to get it 'bagged soon. my momma's bitchin bout all the cars in the yard.

5.7 will basically drop right in. as for the front end im pretty sure its a direct swap. i dont think your gonna need to swap out the rad support though..

its bent to hell on the 94 thats why i was askin(radiator support). thanks.

in that case swap it then.. i was just sayin it isnt neccesary..
