Recently ran a pump gas 445 inch 390 based stroker on the dyno. Mild Edelbrock heads and a BT dual plane. Pulls from 2500-6500RPM. Went from a 750 double pumper to an 850 double pumper with no other changes - back to back withing 15 minutes. Engine picked up 35 horsepower at peak (to 485HP) and lost nothing anywhere.

Go big....
