    Stockish 04 Z71 15.12 @ 90mph

    RCSB 220K mile 5.3. It has longtubes, corsa sport catback, and a vette servo. 32" tall tires that weigh 60# a piece. Auburn pro. Everything else is the way it left the assembly line in 04 (even the tune) . Race weight was 4980 with me in the truck. 48* and a track that was hooking great made for a good day to race and watch. Truck suprised me, I didnt think it had a 15 second pass in it.



    And the slip

    04 rcsb with a few additions.

    Its coming in the near future. Didnt want to tune right now due to the transmission. Its on the weak side, and anymore power I feel would kill it quick.

    A tune wouldn't kill that tranny. It would help it. I'm jealous...my 04 ecZ ran 15.9 with 33's, servo, cai, and tune. So that's pretty good numbers man

    This thing needs all the torque management it can get. The trans is getting really weak, especially in cold weather. Flares at the top of every gear, lockup feels very strange as well. Fluid is black and smells horrible. Didn't want to do a tune and keep it low key due to an ailing trans.

    This truck has been a good one. I havent replaced anything but waterpump, U-joints, and put a auburn pro in it when the g80 died (got the auburn new in box for next to nothing). All the front end components are original and still tight. Still on factory hubs. 4l60e is like I mentioned earlier weak, but still getting it done for now. It hardly ever has any problems, and It gets its fair share of abuse.

    EDIT: Forgot to mention, when the truck had 115K miles, I overheated the trans to the point it boiled fluid out the vent hose.

    Those are amazing numbers. I have an '05 ecrb z71 and it cranked a pathetic 17.0. Granted, it has a little more weight on you, but I don't think it warrents a 2 second difference.
    GET OUT OF HERE WITH THAT RICER MATH!
