New to the forum - seeking advice re: Cams, Increased TQ

I own a '12 Wrangler 4 Door upgraded with an LS3 and 6L80E auto trans. She weighs a hefty ~ 6,000 and is used primarily for rock crawling. Looking for more TQ/WHP and think a cam, tune, upgraded exhaust may do the trick. I want the increased power across the entire range however low RPM's is very important. Looking for 45-60 FT# and same WHP gains.

Any suggestions as to what cam to use, other bolt-ons, and why?

I have contact Vinci HP and they recommended their VHP208 Ultra Torque with specs as follows.......

DUR @ .004" 272*/280*
DUR @ .050" 210*/218*
LIFT .551/.551
OVERLAP 46*
LSA 116*
POWER RANGE 1500 TO 6000
PROVIDES VERY HIGH TORQUE GAINS
GREAT FUEL ECONOMY & POWER
NO TUNING REQUIRED
LIGHT THUMPY IDLE

BTW: Plan on pulling a lightweight travel trailer of (max) 3400#.

Thank you!

What a stupid statement for them to make about no tuning required, what kind a dummy would ever think that is true. Any cam change requires tuning. The computer only knows what it had from the factory and bases all airflow and fueling calculations off that.


That cam would work, should help improve power throughout the power band while keeping the stock stall converter. I would stick with stock exhaust manifolds though, adding headers is going to shift the power band higher in the curve and you wanted to keep the power down low. A good tune and you are on your way.

Thanks for the response.

I will definitely do the tune, also thinking about a 2400 stall converter, your thoughts? Should I change out the springs and rockers? I may get out of this at a reasonable cost.

I think I would do gears . Adding a cam headers or intake is only gonna move the power up the rpm range.
