New guy here from okeechobee fl bought an 03 silverado ss a few months ago and I've been working on it. I did an ms4 cam then sprayed 150 shot and blew the tranny up so I built the tranny with a pro street kit from Dana at pro built with a yank 4100 converter. I switched to electric fans from an 07 silverado now getting ready to turbo so if you have any insight please chime in.
