The overhead cams are easier. You use cam chain wedges to keep the chain tensioner from taking up too much slack. Some zip ties on the chains will keep them in the right position on the gears; then you just have to be careful not to stress the pins that locate the gears to the cams as you R&R the cams. Toughest part is R&R of the valve covers.
As far as I know, K&N fipk is the only intake to have dynoed gains, and that is at the highest revs. No gains from a catback exhaust, exhaust gains come from getting rid of the restrictive y pipe.

awesome tips especialy the ZIP ties (love those) .. would I be able to call up a dodge dealership and ask them for HO cams and an HOintake for 4.7 or is there an aftermarket somewhere beside buying KRC?
Thanks

There hasn't ben a true HO intake since '00 or '01 I think - when the HO motor got a different intake than a regular 4.7. It shifted the power band higher. Then they came out with a compromise design for both. Many mistakenly call that compromise design an HO intake; but to my way of thinking, to be called an HO part - it should be different from a regular part. I suppose those guys think they are running HO lugnuts too ;-)
Many of us with the earlier 4.7's kept the standard intake so as not to give up that low end torque; but a true HO intake was and may still be available, if that is what you want. HO cams can be bought from the dealer as Jeep parts for your year - as Jeep got the HO 4.7 before Dodge. Let us know if you need dimensios for the cam wedges - you can make your own, rather than buying the special tool.

haha HO lug nuts thats too funny...
those dimensions would be sweet!! save money or a headache.. but thanks for that about the intake becuase Ive heard (from other people on this site) that the cams are no use without the intake but I guess thats false. anyways on another note anybody know what this thing will beable to keep up with on the street from personal experiences? remember mines a quad cab

MIKE i tell u the truth i love my 00 qc 4x4 and i beat a qc 2wd bad it had V8 badges but i wish i would have spent the extra money and went with bigger cams.I should not have gotten the trottle body and put the extra $350 to get KRC performance 212x cams the dyno sheets on there web site show 50 hp more with a programmer.NOW the HO cams are good my truck at 2800 rpm to redline felt slugesh the cams made the truck pull through the whole rpm range but maybe only a 10hp and 15 tq gain. I would call marty at KRC performance and just talk to him he's cool.You can get there phone number off there web site
wish i would have gone 212x

Cam chain wedges - cut a piece of board about 5" x 1 9/16". Taper to 1" over 3 1/2". You'll need two. The HO cams will work fine with your stock intake; I felt like the cam change gave me about as much increase as my custom PCM flash - the 4.7 responds well to more ignition advance.

Commonly called the "Mike Leach" flash - had to send the PCM off to California to be flashed. Glad I picked up a boneyard PCM to run my truck in the meanwhile, since UPS (pronounced "oops") sent it to Alaska instead of back to me in Mass. - so it ook a while to get it back. I had to run premium when towing, but could run regular without knock otherwise; until I swapped to 4.10 gears. Then even towing was fine with regular. I've lost the contact info, most guys seem to go with superchips for extra spark advance now. The flash is for '00,'01 only if still available.

About same price as Superchip. I'm guessing they might be similar, but tough to say. I used to know how much advance the Leach flash was and posted that, but no one ever posted how much advance the superchip was to be able to compare. It also raised the speed limiter to where you would never hit it.

All mods work better when planned to work as a package, but you should see a gain without those mods. The only 4.7 intake I've ever heard of that could dyno a gain on it's own is the K&N fipk; and that is only at the highest revs - so the only way I'd bother with that would be if I was racing the truck. The bottleneck in the 4.7 exhaust is the y-pipe, with some worse than others. I think the design differences may have more to do with the vendor that supplied it than the year, from pictures some have posted here. Mine isn't as restrictive as some (not as crimped), so I'm still runnig the stock piece. I still noticed the gain from more ignition advance, I'd think it would be the same for Superchips users. Didn't notice any gain from my catback exhaust, just a nicer tone as a replacement for the rusted factory exhaust. Pretty much what I'd expected, as no one's posted dynoing a significant gain from just putting a catback exhaust on a 4.7.

Ive had a FIPK and now have a VOLANT sealed intake. No huge difference except the K&N seemed to move the power higher in the rev range. Whereas the K& N became made my truck pull like a dog below 3500 rpm but like a banchee above it, the Volant seems to add a little something in a more linnear fashion. PRobably not a huge difference but it feels like it because the gains are more balanced. Whatever you get concentrate on sealing the filter form the engine as best you can and look at ways to pipe air from right at the grill and /or one of the fenders. The routing of the air on the stock intake is not the problem but rather slightly more restrictive tubing and a restrictive filter. ALOT of the higher end intakes make use of a sealed box and get air from the same place the stock intake pulls it rather than just using an open heat shield.
