03_SS_22 Posted January 15, 2009 Report Share Posted January 15, 2009 what are your future goals? idk about the 4.8 but on the 6.0 the stock 4l60e can handle some added power but i would get a shift kit and servos. if your gonna add nitrous or any kind of power adder later then it would be better to get a built unit then looking for a cam look for a 112 lobe seperation (LSA) stock 4l60e i think maybe 500 hp/torque ppl on here with mp112 can maybe get by with a shift kit and a lil bit of trans mods but most go with built units stall depends on the cam but its better to get a cam that matches the stall not the other way around valve springs will be a must Quote Link to comment Share on other sites More sharing options...

Fireman31 Posted January 15, 2009 Report Share Posted January 15, 2009 (edited) There is absolutely no way that a stock 4L60E will ever handle 500ft/lbs torque....in a nutshell, this is what I can think of off the top of my head of what you will need........ camshaft hardened pushrods valve springs larger injectors stall(to match your cam choice) shift kit billet servos allumunum accumulator pistons larger trans cooler LT headers(if in your budget) tuning gaskets, fluids, etc. What is your budget and goals for the truck?

Black2003SS Posted January 15, 2009 Report Share Posted January 15, 2009 Personally, rather than drop that money on the 4.8L, I recommend looking for a slightly used low miles LQ9 or LQ4 and do an engine swap. Right now, you have what? 275-285hp? I forget what the 4.8 has. With a cam and headers and tuning you might see north of 350hp, but not a whole lot more. Depends on which cam you go with and who your tuner is. For the cost of what you are going to spend on a cam and headers, you can find that LQ9 (theres one for sale on the board right now in the classifieds) and slip it right in, still do the tranny mods, have more torque, similar horsepower gains, and much better foundation/building block for the future. Save up your money and do a head/cam swap in the 6.0L down the road, and you could see up to 500hp NA if done right. Its cheaper if you can do all the wrenching yourself. There are a couple of guys who have done it and would know exactly all that is involved if you are willing to turn the wrench. Other than that, Dan's list above looks fairly complete. Good luck.
