I built my snopro last year. Its a 2001 snopro tunnel and bulk head that i fitted 1999 ssnopro plastics on it. I have a BM 680 big bore top end on the 440 A case bottem end. I extened the tunnel and skid out to 144". I have 8 tooth anti racket spockets on it to fit the 2" paddel track on it. I have pods and outwearers on it no airbox, bearcat clutches, 38mm round slides tapered bored to 40mm along with many other mods. She wasnt much when I bought it. Im interested in what you guys are running.
