Just saying HI. I have a '89 1500 with a 4.3L 5spd. I would like to put an ls1 into it and go auto. Just really looking for information and trying to figure out just how much trouble I will run into. I want to lower the truck, get it painted, and do a custom interior. I can do almost all the work myself.

Oh yeah, the truck is on it's second engine and has 335k on it.
