Closed Chamber factory heads, mild porting and big valves
10.5:1 compression
Comp 268XE cam
Performer RPM intake
770cfm Holley Street Avenger

The results were 490 hp and 556 Tq, all below 5500 rpm. I am very happy and think it will certainly be fun to drive! (Now I am really motivated to get this truck on the road!
Chassis or engine dyno?
