Engines » 8.71 BDS blown 474 cu.in. Pontiac 455 pushing 711hp on Pump Gas!

8:71 BDS blown Butler Performance Pontiac on the dyno. 474 cu.in./455 block, very mild HYD ROLLER Cam, 8:1 c.r with 7 psi boost on pump gas.

Made 711 HP and almost 700 ft/lbs torque! Should make a fun little street cruiser... with the AC on!
