Ok I have a 2005 Silverado crew cab with a 5.3L, LT 1 7/8 headers, U/D pulley, CAI, Magnaflow exhaust, 2600 stall, 4:11 gears, built 4l60e, 212 218 low lift comp cam. sprins, CM pushrods.
Ive come across a LQ4 (I swapped in a new motor for it) for free and I'm turning it into a LQ9. I was wondering if I should use the BTR stage 3 truck cam or the BTR stage 4 truck cam. thanks for any help.

 

Depends on your goals. With the 4.11 and the small stall, the stage 3 cam would be fun.

For the stage 4, you would want a stall of around 3000-3500 for it perform as expected.

The stage 4 as that "popcorn" sound that some people like. There are a few youtube videos of trucks with the stage 4 and it sounds mean.

yes that stage 4 cam sounds great. I just kind of want a good cam for the 6.0l, 2600 stall and 4:11 gears.

 

What are you looking for? Low/mid power, mid/top power?

With a 2600 stall that stage 4 will feel kinda bleh on the low end. The stage 3 would work good and it would be torque happy off-idle.

 

that's what I want is the low end and just an overall faster truck. I tow with it about once a month. a 14 foot trailer with a 1250lb side by side.

 

Do you know what you're putting to the wheels or have you ran it at the track?....the 5.3
