I just recently built my 289. I used a comp cam with 512 lift, had my heads redone with 194/160 chevy valves & stiff springs. Also
installed comp hyd lifters. I got 250 hp & 265 torque at the rear
wheels. I think the motor would run better with a 550 lift cam.
Then I installed a used supercharger & am extreemly happy.
With 8 pounds of boost I got 330 hp & 375 torque at the rear wheels. Jay
