I am glad to have found this site, I have a '79 El Camino with around 300,000 on it after using it to do construction work. Needless to say it is tired and needs a total rebuild from the gound up. I want to slip in a LS with automatic and remove the tired 327 Vette engine with turbo 350. The 327 is getting rebuilt to go in my 56 Belair. Can't wait to start.
