Rolled on the throttle from a stop in 4wd. It's 0 to about 75.
Vehicle is 2003 Tahoe Z71 5.3 flex fuel. Mods are LPP LT's, Radix MP112 with 3.0" pulley, CTS-V heat exchanger, 75# injectors, Volant CAI, Kenne Bell BAP, Wheatley E85 tune, Magnaflow 22" muffler, HD2 shift kit, servos, Trucool 40k, stock torque converter, Hotchkis sway bars, panhard bar and trailing arms, Bilstein HD shocks.
I haven't dynoed it in a while, but it made 377/417 earlier (see other videos for dyno pull) with a 3.3" pulley, stock manifolds, and running 93 on a conservative tune. Don't have any track numbers either.
Comments welcome.
Are you using stock transmission?

@6824096 Yep, stock 4L60E with a corvette servo, Sonnax billet 4th gear servo, aluminum accumulator pistons, hardened Transgo separator plate, Transgo HD2 shift kit with no washers and TruCool 40,000 GVW trans cooler. And 70% torque management left in, which I think is the real difference maker.
