Re: 4.7 Mods Suggestion - Performance

Mopar H.O cams and valve springs will be a nice upgrade. 25RWHP gained. I had them in my 07 4.7 and it really woke the truck up. Definatley noticed more power with the cams when i had the superchips tune installed.

Re: 4.7 Mods Suggestion - Performance

The cams can be found dirt cheap from Henson.

If you dont want to tear into the motor, a intake, 3" exhaust w/ high flow muffler of your choice, and a bigger TB of your brand preference is a solid start, and well within the PCM's ability to understand. The 2003-2007 PCMs arent as forgiving to modifications as the earlier models are.

Re: 4.7 Mods Suggestion - Performance

^^^^^yeah...over $300 cheap...plus the springs. He's only asking $200 for them...which is cheap IMO.

Re: 4.7 Mods Suggestion - Performance

K&N 63 or 77 series. The ones that remove the air box thats mounted to the TB. 90% of the other intakes dont do that.

Re: 4.7 Mods Suggestion - Performance

You could go back and forth on the oiled or dry filters all day and into tomorrow. Ive used both on different vehicles...not really noticed any sorts of differences.
