I am installing WCCH Stage 2 heads, LPE GT2-3 Cam, Chromemoly push rods, LS6 springs, and a Radix Supercharger in the next couple of months. I need suggestions on what else I should replace while I have the engine pretty much tore apart. My engine currently has about 55,000 miles on it and all of my mods are in my sig. Thanks in advance for your suggestions.

 

get that tranny upgraded cause it prolly wont last under that kind of power

 

I started with the exact same mods...I was the unlucky one who just kept destroying the 4l60e (3 times). At the very least put a kit and servo's in that trans.

Man, heads, cam, TT3000, eaton posi, 4.10's, radix, 3.2 instead of 3.4...some may argue, but bye bye trans. Do alot research on the 4l60e and see what kinda of money you want to put into it...if any at all.

Good mod list though, RCSB and those mods, you'll be happy...it will haul ***.

 

Trannys gonna ****!!!!! Big time.

 

My suggestions:
Water injection. Helps inhibit detonation and cleans carbon build up (which also is key in preventing pre-ignition). considering your tuning will probobly be off- this is a good thing. Which brings me to my second point

TUNING this is more than 3 hours on a dyno. this is you learning how to tune and getting some software. Spending any time you can tuning. This is CRITICAL to durability and part throttle performance (power, responce, gas milage etc). Its more critical to durability since your pistons cant STAND detonation

depending how far you want to go, ceramic coating is cool. Polishing the chambers and pistons help prevent hotspots and pre-ignition.

 

Yea I know all about the Transmission problems I will have. I have already done the HD shift kit, servos and other misc. stuff but I dont think that will be enough to save my 4L60E from what I will be putting it through. Besides the Transmission blowing up is there anything else that I should do while I have the engine tore apart?

 

Yea I know tuning will be another big challenge with my setup, I will probably bite the bullet and take my truck down to Lingenfelter Performance Engineering and have them dyno tune my truck. It will probably cost alot but it would be worth it in the long run. Thanks for you suggestions.
