    Looking for a nice performance cam with a choppy idle and street power for my 2004 CCSB Z71. Current mods include a BBP Traditional tune, Vette servo, 3.73 Gears -(going to change to 4.56 ring and pinion), a K&N 77 FIPK, a cat-back Flowmaster dual in and out exhaust system, a 6 inch lift with 20X12 Moto 962's with 33X12.50 tires. I don't tow anything, or go off-roading, but going up a slight decline, I can feel the weight of the lift and wheels/tires making it downshift and struggle a bit. I like what "11MPG" recommended by installing a 216/222, 111 LSA, 222/216 lift. I wonder if it will be okay to drive with this before tuning it? What symptoms will likely occur after the cam install? I'll be getting LS6 springs. Do I need new pushrods? I currently have 127K miles on the stock 5.3L. The engine will be also getting a set of LT's with an off road Y-pipe possibly Pacesetter, Texas speed LT's, or Speed Engineering LT's. I'd like a nice noticeable choppy idle, good throttle response, and power from 1500-5500 RPM's. I'll be getting the auto-cal from BBP so Justin can make the tuning changes.

    i woudnt drive it much before you tune it. I probably put 200 miles on mine before i could get it tuned (212/218) .599 112lsa and it was fine. Do the headers and everything first, i went with speed engineering and they were pretty decent for the price.
    Cam should work pretty decent for that application but the biggest difference will be the gears

    would probably get the BTR truck stage 3 or a vinci trucker cam. ether of those would be nice with a 3200rpm stall and yes new push rods would be needed to replace the stock ones.

    also would choose a spring recommended by the cam company.

    We have a 40,000 miles on the 216/222 duration 111 LSA cam in my buddy's truck. Stock pushrods and LS6 springs. Still has the factory stall and the off idle toque feels stock but it changes at 2,500 and at 3,000rpm you hit a real motherfucker of a torque curve. Major bonus of the low LSA alone with the heavy thumping idle it gives. Downside is the overlap burns more fuel and you don't get as much top end as a 114 LSA. End of the day though I highly recommend that cam for anyone that wants to make noise and make killer torque.

    As for the tuning it'll run shitty without the tune but it'll run. If you have trouble idling pull off one of the vacuum lines to the valve cover and it'll bring the idle rpm up. Temporary fix. Make sure you re-attach it though before you data log.

    To Bobfig, Carter, and 11MPG, thank you for the replies and for your knowledge. I decided to get the Detroit TrueTrac Differential, and either a Yukon Gear set ratio of 4.10 or 4.56 (Undecided-I don't do that much interstate driving-I wish Yukon offered 4.30 Gears) first. Secondly, get long-tube headers (deciding on whether to get Ceramic coated or stainless steel), then a Auto-Cal from BBP, then the 216/222 cam installed with a new water pump, valve springs, gaskets, and a ARP crankshaft bolt.

    I would stick with 4.56s truck will be a lot more fun and the speed engineering stainless LTs were good quality as far as build just had to do a little adjustment on the driver side due to rubbing on the frame but I heard its from saggy motor mounts

    I have 05 Sierra 2wd crew cab, 5.3, long tubes, NNBS intake & injectors, airaid intake, GTO 90mm TB...

    I am trying to make a decision on a cam, and gear set. Anyone have a solid suggestion? Looking at Texas Speed stage 3 low lift cam and 4.11 gear set

    I'm looking at the btr stage 3 cam for my 05 5.3 z71. I want idle to 35-4500 mostly. I have 4.10s and heavy wheels and tires. Is that a good cam for dd? I'm 90% highway and 10% city. I do pull my Yukon on a trailer occasion
