Not running webers - maybe further down the road!! But my 331 KC stroker was built with AFR 165's - and dynod on the stand at 446 hp at 6000 rpm. On the chassis dyno it put down 326 HP to the rear wheels. Smaller valves than the Twisted Wedge .. but greater overall flow due to higher velocity. I'm told velocity = improved fuel air mix and power.
