View Full Version : 99 RCSB Z71 LS1-Heads Cam-Built 4L60E-3000 stall. Needs alittle TLC

05-04-2012, 10:36 PM
I have a 99 Silverado Z71 with 2001 LS1 out of Z28 52k on motor.
Engine: 01 LS1 Short Block with ARP Rod Bolts
Heads: PRC Stage 2.5 5.3 Heads 225cc intake runners with Double Valve springs, titanium retainers.
Cam: Comp LSR 227-243 614-624 lift on a 114. TSP 7.4 harden push rods.
Intake: 2004 EGRless Intake. It was ported at the intake runners to open them up alittle for the heads. It has a stock Ported and Polished throttle body. Also has 42lbs Marine injectors.
Transmission: Out of 2005 silverado 4L60E Beast Sun shell, Kevlar clutches, corvette servos, Trans go shift kit. GM Performance Parts 3200 stall. Has 3:73 front and rear with G80 posi. 4 wheel disc. Has manual transfer case not push button.
2001 Yukon Denali Gauge Cluster. (mileage and Shift Selector doesnt light up)
Has LS1 Fans, Shorty headers with cats removed and a 3" banks Muffler.
Body does have a few dents one is bottom of passenger door and rocker panel and passenger side right on the Z71 decal. I will post pics of them later.
Trucks runs awesome but does need alittle work like dents fixed and roof and hood clear coat fading. But I do have alot money in building the LS1 and 4L60E. Chassis has around 200k on it, LS1 ShortBlock has 55k on it, heads and cam 4k. Trans about 8k. Will come with the Factory 16" rims and tires and a set of BBS 18" with a set of 255/55/18 and a set of 265/60/18. $ 5800 OBO.

Here is a little idle clip. (

That truck probably surprises quite a few people

Big Time. I havent ran it at the track because I havent had a sticky set of tires but I have ran a few cars on a roll from 50-60 or so and it rolls. It will spin the tires as long as you want to hold the throttle down. I ran my friends 04 Z06 bolt on car. and from 50-135 I was right within a car of him the whole time. I would say being conservative say it is 12.0-12.5 N/A. With a good tune in it and a better intake and throttle body it would pick up big time.

Taking offers on trades as well. Let me know what you got.

Bump pictures of the engine were added, doesn't look much different than the factory engine, I took a picture on the passenger side by the head so you can see that the block is aluminum.

interested. why not launch it in 4wd?

05-21-2012, 06:09 PM
I was worried about the tie rod ends. That what I see break on some of the duramax trucks. I have did a few little launches but no full on pulls. I have never had it at the track or really anywhere were I could do it. I know my drivetrain will take it transmission is built badass and the front , rear and transfer case have all been on thru when I had the transmission built, so I know that won't be a problem.

Does the A/C still work?

06-08-2012, 10:46 PM
A/C does work.

bump!!! Should have Silverado PCM tuned by the weekend, then there will be no more problems with the ac system not getting power and the security light will be fixed because the truck will not think its a Camaro anymore.

07-02-2012, 12:23 AM
Ok silverado pcm has been tuned and reinstalled. ready to go

If it was a 6 spd, i might but I have 1500 bucks in my 4L60e so it would hold up to the LS1. been there with the A4 in my 2001 Z28 with a Rossler stg 3, No more autos for me.
