Lag not!
This is a 6.0 SBC with Twin 76mm Turbo's on it. Stock Crank, Rods, Pistons, Heads & Manifolds.....
Hang on! There are a TON of SBC guys running in the 8's with no more that a Stock 5.3 or 6.0 Litre with Twin Turbo's using an LS6 Cam with new valve springs on the Stock ECU & a Custom Tune..... Most of these guys have no more than 4K into the whole Engine with the Turbo set up & everything.
