1971-95 Banks PowerStick Cam

Banks’ High-Performance Cam-and-kit elicits outstanding improvements in Power and Torque output from 1971-95 Chevy/GMC 454-ci (7.4L) trucks, Suburbans and motorhomes. The PowerStick camshaft’s precision-engineered lobe profile compels peak performance and better mileage from V-8s.

Banks PowerStick can be purchased separately, but Chevy big block owners who crave the ultimate select Banks top-tier PowerPack , which includes the PowerStick assembly.

The PowerPack-and-cam’s full complement crowns 454 engines with up to +104 horsepower at 4300 rpm and bench-presses another +93 lb-ft torque at the critical downshift point. That big dose of progress turns yesterday’s V-8s into today’s Vortec-beaters!
