So tried searching the forums and didn’t get much luck, got a 2000 Classic K2500, motors been drinking oil (454) and waiting for it to blow, but now the trans (4l80) is hard shifting, so I wanted to do a 6.0ls with 4l80, but I found a Allison trans with transfer case for $1k. Is the Allison possible? Worth it? Engine and trans will remain basically stock for the time being. Eventually pulled for mild build, maybe boost. Who’s the go to for wiring? And brackets? I’ve seen plenty for the 1/2ton trucks but can’t find much for the 3/4 tons. Thanks guys!
