Default Performer RPM vs. Victor Jr.
Just wondering what your opinions are on the victor jr. intake vs. the performer rpm intake. We are currently running the performer rpm with good results, but when i change the intake from dual plane to single plane on desktop dyno it shows a rise in hp from 415 to 450. The loss in torque at 2000 rpm is minimal (301 ft/lbs vs. 320 ft/lbs).

The engine is a 331 stroker with world products 180cc alum. heads, hyd. roller cam .560 lift, 234 duration. holley 650 double pumper with mech. secondaries.

Any advice would be greatly appreciated.

Thanks,
Glenn
