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.

The Stage 4 grind is a popular choice for those looking to delete DOD/AFM, or just add some pep to your trucks step. With great power gains and OEM driving characteristics, this camshaft works well with an upgraded torque converter. This camshaft WILL FIT WITHOUT FLYCUTTING! 

This 217 intake duration cam is BTR's largest recommended offering for a L83 with unmilled cylinder heads. With just simple bolt-ons this grind has made well over 500hp in a stock bottom end application. It's truly a marvel in its ability to perform well in such a mild application. By continuing to utilize the factory intalled VVT system, we were able to set the valve events where we like for stump pulling torque down lown while providing EXPLOSIVE top end power. In this sense, the end user truly has the best of both worlds.

Made In The USA!

NOTE: This camshaft requires valve spring upgrade, part number SK013
