After doing some reading, and PMing on some parts I've come to the choice of doing Efans or a mild cam next. I'm leaning toward fans now. It looks like price and less hassle. Big question is can I run them without having my tune changed. Just got the tune done, should have had the e fan pin turned on but didn't think I would be doing them this soon.

So opinions.

do the cam

do the fans

cam. you wont see as much from the fans. a cam will completely change your truck.

I vote cam. Cam makes a noticeable difference, both in performance and sound. And the swap isnt near as bad as you might think.

and insalation will take about 15-30min

Fans can be had for 80-100 bucks vs ~$600-700 for a cam swap (400 cam, 100 pushrods, 150 springs, gaskets, fluids).

So it all depends on how much you want to spend, what results you're expecting, and how soon you can get a retune.

Electric fans can be wired up to a manual switch, so a retune wouldn't be necessary right away. But the only difference you will notice is that it will rev a little bit faster, and you might get better gas mileage. There isn't too big of a performance gain, but you won't hear that annoying clutch fan wooooosh noise when the truck gets hot.

If you get the cam, you'll spend all day installing it (assuming you're competent to do it). It will drive like absolute ****, and with a 5 spd it might be even worse until you are able to get a retune. The truck will be faster, but that depends on the cam you get. I'd also seriously look at a set of longtube headers to go with the cam swap.

Put LTs on last week. I'm competent enough but I'm expecting a little over a day on it. I was looking for a little more down low but I've read as far as cams go in the 4.8 your going to lose some bottom end. Good daily cam. Thanks for the input I'm going to roll it over in my head a bit more. Search more on cams and try to pick something that is going to be close to what I want.

Yeah it will run like complete **** if you get a cam worth swapping, mine would die at every stop sign/light when I stepped the clutch in. Got old REAL fast.
