Hey guys, looking to get a bunch of helpful info form people that know what they are talking about and this looks like the best place by far to get it! I want to build a low to mid 11 sec DD and i need help figuring out EXACTLY what i need to do it. Truck is an 05 LLY that made 541whp on the dyno but thats not enough for me. I was thinking about twins and a built motor but what do i need in the motor for it to live a long and healthy life? I am thinking rods, cut and coated pistons,and head studs but after that i have no idea. Would up pipes and manifolds be a good idea? I am guessing i'll need 750-800 whp to meet my goal. Any info you have to offer will be MUCH appreciated.
