ok im thinking about buying an 86 chevy long wheel base. it has a 305 and a 3 speed with granny. what would i need to do or what do i need to swap in a ls1 or 6.0 motor into the truck? harness? drive shaft? motor mounts? radiator? all the good stuff. i have so im told a 98 ls1 wiring harness with computer fuse box and everything. will that work on a truck motor or will it work at all?
