Hello friends, I have a chevrolet tahoe 5.3 LT 4x4x 2000, with K & N air induction system, 6 inch lift, 315 / 70r17 tires and 17x9 tires. It was made a change of axle ratio, original 3.73, now ratio of 4.56 in both axes, calibration with a hypertech (performance fuel premium / regular, speedometer calibration, speed limiter with index of new tire, reprogramming new relation of axles and tires ). The transmission box is the 4-speed 4L60-E automatic, which says it supports up to 360 ft. lbf (488 N.m) of torque. My vehicle by catalog offers me 325 ft.lbf (441 nm), I want to make a modification and optimize it, to reach about 355 ft.lbf of torque. Investigating out there, they say that by changing the camshaft and torque converter I can improve on what I want. At the same time, I will have to change valves, pistons, valve spring, or something else to reinforce ????.
I hope your opinions about this, since I want to make the change without any inconvenience to buy what is necessary and not damage the engine or the transmission box.
Regards!
