My bro runs Comp Thumper cams with stock springs. They sound bada$$ but he only gained maybe 15 hp with them.

I think you may have heard wrong. Cams can do wonders, given the correct supporting mods. What mods do you currently have?

Not a huge gain. Keep your stock sticks and save your money unless you have every other imaginable bolt on already.

With LTs and O/R with catback exhaust and CAI, I added UDPs, ***** Thumpr Cams, and CMCV delete plates. I gained 50 rwhp. If you want to do cams, make sure you have gears to support them. I have 4.10s.

Nice gain!
I gained about 46RWHP with long tubes, high flow catted x... but I also had 4.10's put in which actually lower the numbers on the dyno even though it makes you quicker.

Cams with LT's at a minimum for thumbs-up gains.
