Brian Tooley Racing, or simply BTR, has become synonymous with aftermarket LS and LT camshafts in the racing world. You’ll find a lot of their custom grinds under countless vehicles at events such as LS Fest and Street Car Takeover, and a few have even ended up in a project or two of ours over the years. Ā However, their latest creation is one designed for the GEN-V “LT-based” truck crowd!
Official Release:
The ALL NEW Gen-V 220 Camshaft
These units are the culmination of extensive in-house Spintron testing, coupled with thorough vetting on our Superflow Engine Dynamometer. We have spent countless hours designingĀ some of the most stable, powerful lobes in the industry.Ā These camshafts have been extensively tested against our competitors’ designs, and have shown better valvetrain stability, yet make more horsepower and torque as well. All this translates into better longevity, less valvetrain wear and tear and more power.
The 220 cam is truly a marvel in it’s ability to perform in such a mild application. With just simple bolt-ons this grind has brought a new dawn to the L83 5.3L, as well as enormous gains in the LT1/L86 6.2L. By utilizing VVT we are able to set the valve events where we like for stump pulling torque down low while providing EXPLOSIVE top end power. All of which is made possible by utilizing VVT control beyond peak torque. In this sense, the end user truly has the best of both worlds.
NOTE: To take advantage of this grind, it is imperative to utilize VVT control when tuning. A proper calibration with attention to detail in this respect, will make this camshaft SHINE!
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.
Features:
- Immense Power/Torque Increase
- More Valvetrain Reliability Compared to Many Competitors
- Awesome Upgrade for NA and Boosted Applications
