This unit is the culmination of extensive in-house Spintron testing, coupled with thorough vetting on our Superflow Engine Dynamometer. We have spent countless hours designing some of the most stable, powerful lobes in the industry. These camshafts have been extensively tested against our competitors’ designs , and have shown better valve train stability, yet make more horsepower and torque as well . All this translates into better longevity , less valve train wear and tear and more power.
This does not come without a small sacrifice to the 5.3L crowd, as you must fly-cut your pistons to allow for this grind to properly fit. However, a DOD delete is also necessary, which means those cylinder heads have to be removed regardless. One extra small step to provide enormous gains across the powerband.
