The Truck Plus will add 75+ hp over the stock cam in a typical 5.3L application. More power from 2650 rpm up making it a great choice for those wanting more torque and horsepower. The 585-lift Truck Plus cam requires .600-lift springs, which are included in this kit. The Truck Plus cam can be used with a stock converter but will perform best with a higher than stock stall converter. This cam has been extensively dyno tested and has been run successfully NA, with every type of blower (centrifugal, roots and twin screw) and with a Turbo(s). This cam works very well under boost and requires a tune for maximum performance.

Recommended spring for our Truck Plus cam is the new RHP Beehive valve springs. This is a great option for camshafts using less than .600 valve lift. This valve spring is designed to use the factory retainers and locks.

Good quality and pricing. Appreciate the constant communication. Excellent customer service.
Richard Dyno tests don't lie this cam is a good middle ground. down low it still has that low end torque, but all the way to 6200 it screams. I'm running it on my 86 C10 with a LM7, 2600 stall converter with 3.73 gears and it's great. You can hear some chop but its still very drivable with a lot more power on the top. Typically past 5000 stock truck motors feel dead, but with the cam the power band is phenomenal. I Highly recommend this cam for street cars that are gonna see some traffic and daily use, you will not loose any real low end but gain a lot at the top end.
The truck plus cam gives great torque/power.
