My dads engine in his 93 Silverado 5.7l is starting to crap out and I told him to throw in a new 6.0L. Figure less problems with it. I was wondering how hard would it be todo that. Being that we would install it our selves. I know i would have to swap out the the trans, but the thing is the electrical. Hooking up the gauges seems difficult among other things.

 

Lot of work and money but worth it no doubt. Check out LS1Truck.com, few guys there have done this type of swap with great results.
