Hi everyone, I feel I'm a bit late to the game and wish I would have gotten into this stuff long ago. I'm an import dealer tech, but old school hot rods are my passion. After selling my 49 Plymouth because the stock drive train wouldn't go much over 55mph, I recently purchased a 52 Chevy 3800 that sits on a 2005 GMC van chassis, it has a 4.8/ 4l80e. I bought the truck already put together and there was DLC. I wanted to be able to look at the data so that's where it started for me and here I am.
