Hey guys I have a cast iron block 6.0 with Wisecos K398x3 pistons and 6.125 h beams,ARP main studs,ARP head studs,gonna run my 317's and was told to run a LS9 cam for turbo,was also told to run a S480 Borg Warner.Now this is my first turbo build im tired of filling nitrous bottles.From what I've read there's more to just buying a turbo,I'm hoping to get some help from someone who's been down this road before to pick right turbo the first time.The comp ratio will be 10:1,truck gets Street driven&raced,also goes to sand dunes to drag race&climb hills.It has 4.56 gears with 35" tires,built TH350 with a TCI Street fighter with stall speed 3500ish.I have 6.0 cast iron manifolds if needed,ported TBSS intake.Twins?Twin scroll single?Single turbo?Thanks!
