new to LS1 tech
Couple questions:
What are your goals?
What is the truck for? drag? street? autocross?
Any wants to need? like intakes etc?
Budget?
What kind of fab skills do you have?
to start, I would do flipped 2010 camaro manifolds, and either gt3076 or gt35's for turbos. 80 lb injectors, HTptuners, supporting fuel system mods, Head studs, ls9 gaskets, a cam( either used or a custom spec depending on budget, supporting valve springs, treadstone TT intercooler, RPS BOV, a pair of wastegates of choice ( tial, JGS, precision)
Do an 4l80e with HD2Kit and a good 3 disc lockup stall.
Crank up the boost if its too slow( i doubt it will be though)
