Hi, I am in the process of restoring a '84 El Camino SS Choo-Choo Custom. My Dad is the original owner of the car and has given it to me for my first car. This was his daily driver until 3 years ago and has been sitting out in the elements since. It has the original 305 that came in it but the transmission has been swaped for a TH350. We had the front end rebuilt a few months ago and I am now working on a 350 out of '92 Silverado Z71 to put in it.
