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.

Packaging was good, got parts in excellent condition. Will be a while till motor runs and get to test real life output. I have watched Richard‘s videos for a few years before choosing this cam. With the Big manufactures selling off their businesses we decided to try one from the guy that shows us true results. Richard is a straight forward type of guy and truly have learned so much from him, Seems the right direction to go for an aggressive/street truck. That will be happy cruising or aggressive (6.2, gen 4, 8hp build) I will update when we get it running but satisfied on our choice for sure at this point.
Used this on my own race car.. and it was 2x better then the cam i was using before..... and now i used one in track car #2
I put this cam and springs in my 5.3 ls swap i couldn't be happier i also used the rhp tuner to tune my truck it makes good power and sounds mean
Shipped fast and the packaging was great.
awesome
