I am about to start building a 04 lly, never built one before but the time has come. I was thinking carrillo rods, mahle pistons, arps, hamilton cam, pushrods, and valve springs. what else is critical in a duramax, ive built a couple cummins motors. this motor is going in a 4 door 1 ton single wheel, with 35's. the guy wants to make 650-700 at the wheels and wants it to last. let me know what yall think.
thanks
