Certainly possible. My combo is a 4.15 stroke in a 400 block for 500 ci. Made 550 HP at 5100 rpm and 610 torque at 4100 rpm, with pocket ported 452 heads. Torque was over 550 ft/lbs from 2700 to 5200 rpm. Cam is a comp hydraulic roller 236/242 duration 541/544 lift. Intake was a Holley Street Dominator with a 750 DP, but a Performer RPM would work the same. I am in the process of changing to Edelbrock RPM heads. The stock heads flowed 250 cfm but nosed over after 400 lift. The eddies keep climbing, so I'm interested to see what difference they make in total HP and rev range. It wont go back to the dyno, but I have a good baseline at the track to compare to. Price, who knows, I never added it up.
