I've got a 86 GMC Sierra. Original 305 is wasted so I'm considering tossing in a LT1. Anyone here ever done it? I tried to do a search but it wouldn't let me search for LT1.

I know the engine will physically bolt in, it's just the little stuff I need to know. Like, does it have a weird EGR setup using a seperate pipe coming off an exhaust manifold? What have people done for the fuel systems? Can a rear tank be mounted in these trucks, like from a Suburban (my truck is a longbed)?

If anyone here has doen it and has any info on it or even some pics it would really help.
