You need to contact a cam company and give them all the info so they can design/choose one for you. (tire size, weight, gear ratio, converter stall, etc)

I went to the comp website and filled out their form and a comp cam representative got back to me saying what cam I should go with.
Did he suggest going with new lifters? You should......
Big Buttons
The SS Burb
Yes because the lifters on these motors are NOISY to say the least.

Also when you do the cam get hardened 7.4" pushrods, you will have to do valve springs more than likely, depending on how much lift you go with you may have to do dual springs ( I had to do dual springs) along with new valve seals, seats, and locators.
If you need help finding parts holler at me and I will give you the websites I bought my stuff from. Cheapest I found.

If you can find a valve spring kit then get the kit. If not you can part it together. I went with the PRC Dual Spring kit. This kit http://www.hawksthirdgenparts.com/products/PRC-Double-Valve-Spring-Kit,-Good-up-to-.650"-Lift.html Good up till .650 lift
For parting it together.
Springs good up to .600 lift

If you need to go with the Dual spring set I recommend the PRC kit. It comes with everything you need. Just get the pushrods and lifters. I personally didn't get lifters but if you have a higher mileage get them (peace of mind).
Replace all the gaskets that you will be touching (water pump (2), timing cover, front seal, head gaskets if you take heads off (I didn't)) Fluids-coolant, oil (make sure you get zinc additive for the first 2-3 oil changes), gonna need a qt of trans fluid if you taking out radiator.
That's all I can think of right now. Any other questions just ask.... been all inside these motors.

No problem at all man. What do you want with this cam? Take off, midrange, long run?

how'd you change the lifters without pulling the heads ?
Big Buttons
The SS Burb
I didn't change lifters.
I really just want to get better performance then stock overall. Im not trying to go crazy with it. Im thinking about a good balance of power and torque. More of a sport feel then a muscle car... if that makes sense.

Make sure you tell them that when you do that questionnaire for comp or whoever you ask.
There is more to it than just filling out a card and having comp grind you a cam. What are your goals for the truck. Do you plan on putting a stall in the tranny. What other mods do you have. Do you even have long tube header. With out supporting mods, when you swap in the cam you can only expect to get 10-15 more HP. The truck will also need to by dyno tuned so it will drive correctly.
In your case i would not even bother with a cam. Get what are called bolt on mods.
1 Full exhause with long tube headers
2 Port and polished throttle body.
3. Under drive pulley,
4. cold air Intake
5. LSX intake manifold
6. Full dyno tune.
You can expect 30-40 increase in RWHP with this list. If you want more HP expect to spend another 2k for heads and cam. You will also need another 2k for a tranny that can handle the HP.
