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.

I have yet to actually run the cam but the quality is par for others on the market and half the price. I did not have a spring tester to check the valve spring deviation but they also appear to be quality with the coils measuring almost exactly the same
The truck plus cam shaft and spring package I got from Richard is very high quality! This cam is going to make my drag car boogy down the track. Will also be getting the Rhip1200 G42 turbo when funds become more available. Can’t wait for my sons and I first season of drag racing!
Product was packaged great and shiped fast.
The price you see on the site is the price you pay
Enough chop to know its there and the power gain over factory is noticeable. Very pleased with product, price, shipping time, and customer service.
Eveything arrived on time and even came with a sticker! Cant wait to get it intalled and under boost!
