    This truck was a 10 year home build that started as a 350/350 heavy duty 1/2 ton. The only original parts left are the basic bare frame, cab and front fenders and tailgate. It now has a mild nitrous fed date correct 454, 3000 stall turbo 400 with an 3:73 posi 12 bolt which make for a nice street mannered combination . As being a licensed tech except for final paint it was built in our 2 car garage . It definitely gets a lot of attention, has been fortunate to win a lot of awards at shows and been featured as a cover truck on the LMC Catalogue a Couple years ago. It now rides on 20” wheels and has been lowered approximately 6” front and 8” rear with drop spindles, front and rear springs and hangers and now handles like a go cart. The 454 has been upgraded with home ported and polished heads, roller rockers and proper springs for the cam.
