461c.i. Pump Gas Pontiac EFI Street Engine 620 HP & 600 ft.lbs of Torque w/o nitrous! -- 780 HP & 835 ft.lbs. of Torque w/nitrous !!!
This beautiful, ready to run EFI Pontiac Engine from Butler Performance is going in a customer's show quality and regularly street driven 1967 GTO. He wanted 600 Hp on pump gas with the streetability to be driven anywhere, as well as utilizing all accessories including AC. Just for fun, we added a small nitrous kit that works directly with the EFI - No separate fuel system or regulator needed, with only the main nitrous line to hook up. We even included a tuned nitrous MAP and control in the EFI so the customer only has to turn on the bottle, flip the arming switch and hit the gas(PUMP GAS! no fuel mixing required with the EFI). We also added one of our Evac Pump kits to insure years of oil leak free use, even with the extra cylinder pressure of the nitrous.
