My truck has a 5.7L vortec. It’s a single axel 1999 c3500. Need to swap. I’ve been undecided on a crate ht383e or something with some ummph like an LS crate. Trying to find out if I am getting in over my head with an LS swap. I’m older and haven’t educated myself so I’m not as familiar with chips injection and harness more use to carb and a power glide. Your help is appreciated.
