Hello everyone, my name is Sean. I have been a long-time square body chevy guy and own 5 of them. I am also into old mechanical Diesels. I like saving old trucks from the scrapyard and rebuilding them. I'm am new to ls swaps but enjoy doing everything myself and would like to learn. Reprogramed my first PCM yesterday and would like to learn more. Currently I'm swapping a 5.3 out of a 2006 chevy 1500 into a 1976 gmc shortbed. I hope to learn more and eventually be able to help others.
