The community can help you pick a cam, but we will need some more info.

What is the year of the truck and is it RWD or 4WD?

Does this have VVT and AFM/DOD?

If you have VVT and AFM are you wanting to keep that or are you getting rid of it?

Are you wanting a drop-in cam without changing valve springs? Do you know the mileage on the engine?

Are you using the stock torque converter and gears? Are you willing to change those?

The more info you provide the better we will be able to provide a camshaft recommendation.

Our Stage 2 cam (link) would work well for that. It's a cam that is mean to work with headers but retain a stock stall. We've been moving a lot of truck cams lately which is cool. We spent a lot of time on the specs and local development, good driveability and low end power is important to us, especially in heavier street/daily drivers.

I am an *******, I freely admit.

@stock48 @03sierraslt can make a great cam recommendation for a rockin idle, cut on a 106-109 LSA, have great off idle pull but more times than not, guys will go get a ms4 cam and wonder why the fkn tires won’t roll over with their 2k stall.

Tell me when I’m wrong.
