8.1 vortec hot rod! - ls1tech
Hello guys, i have an odd project. i have avery nice 8.1 vortec engine i want to get more powerful and a lot cleaner than it looks today. i know its a step back to.
I just bought a 8.1l what the hell is it? and more
So my cousin works for chevy and recently a 2500hd with a 8.1l came in with lower end noise. he found it had a bad bearing but everything else looks great..
