hey guys, i know this isnt for trucks or anything but for some stupid reason i can put a thread on ls1 truck. anyways, i was thinking about getting a single cab 4.8 chevy or gmc and getting a 6.0 on the side and putting some 243 heads and an ls6 cam in it and keeping the vortec intake and just put some shorty headers on it with h-pipe. would that be worth making a sleeper out of. and what possible hp and torque ratings would i be looking at if anyone has an idea. just trying to get an idea. all help is appreciated. if not then thanks for taking the time to read.
