We need one post for everyone with the HO cams.
I for one have not installed yet and have fielded several questions on other llinks. I would like this to be the one stop post for everyone with questions and tips.
So here are my questions:
1)Where can I find instructions mine were shippped with no instructions
2)Can we get away with not using the special spanner wrench on the install.
3)What are the true performance gains of this mod?
4) how long does the install take for the average Joe? What are the tools required.
Thank you in an effort to slow down the confusion and disorganization I think more of us should post under headings that are related rather than start our very own post everytime we have a question.
I admit I have been guilty of posting my own post in the past but come on guys enough is enough...I know some of you guys (like me) sneek a peek at the boards sometimes when you are at work....it would be nice if you could spend five minutes finding the info you need rather than the usual 30 it takes to wade through the garbage.

I agree. I have not installed mine yet due to some questions not being answered. Somebody said to use the crankshaft bolt instead of having to use the spanner tool on the cam sprocket. Also, one post said you had to remove the power steering pump, including disconnecting the return line. Can you just remove the bolts and move the pump forward enough to get the torque wrench on the cam bolt?

The illustrated instructions are posted on the Speedtweaks.net website under the tips & tricks section.
If you dont' want to do that, you can order them with the wedge tool from Marty at KRC Performance. It costs around $20.
Really all you need to do for the PS pump is loosen enough bolts to rotate the reservoir out of the way. Do not remove the reservoir, as you will spill PS fluid all over the place and probably damage the o-ring seal.
As for holding the cams in place, you can use a long breaker bar with the appropriate socket on the crank pulley bolt. Hold this in place to keep the engine from rotating (a buddy would be helpful here), and you torque the cam sprocket bolt against the resistance from that.
If you have a 5-spd truck, you can leave it in 1st gear and set the parking brake really hard. The cam sprocket will be trying to rotate the entire driveline, and you will hit 90 ft-lbs before it will rotate the camshaft itself......

alex,
so is that all the spanner tool is for is to hold the cam still while you torque it?
(i.e. using that trick you just said, do we still need the special tool?)
thx

That's correct. You won't need a spanner wrench if you do either of the techniques that I mentioned.
You may be able to borrow a spanner from a tool rental store, but it may not fit the application.... i don't know.

You WILL need that 8350 Chain wedge tool...there are plenty of guys who have this now so you might want to check with someone who has already installed for a loaner wedge...now if someone had the more expensive spanner wrench hahhaha

I found a fix for the spanner tool. This takes a little work, but is much cheaper than the actual tool. I went to Harbor Freight and bought an $8 oil filter wrench. It lookes like a pair of pliars with big curved teeth at the end. Then I went to the local hardware store and bought a piece of steel rod in 1/4 diamater. The holes in the cam sprocket are actually less than 1/4, so you will have to grind the rod down a little bit. I cut the rod, but the piece in a drill and had it turning while I put it up against a grinding wheel. This produced a nice smooth and symetrical pin to go in the cam holes. Tack welded the pins to the pliars and had a spanner tool for under $10.

The more I think about it, the more I'm wanting to go ahead with it ... sooooo ...
who can tell me the part number for the HO intake manifold off the Jeep?
My dealers up here are a bunch of tits and can't look up anything unless it's 3 years old or they have the part number.
thanks

Okay guys, almost done with the cam install and here are some tips.
1. You don't need the spanner tool. I just used a ratchet and 2X4 to lock the crankshaft bolt. Worked just fine.
2. You will need 2 sets of hands to get the head covers off. Getting the bolts out is easy, getting the covers out is not. The big black drum thing on the left side that is part of the brakes is in the way, and the fuel line where it attaches to the fuel rails is in the way. You can get the cover out without removing those things, but it is a bitch by yourself. Get a friend to help with this step. The Right side is just as bad with the a/c lines. I moved the compressor to the side, but it is still EXTREMELY tight and again a second set of hands helps. Also, the bolts are held into the cover with a rubber grommet thing. Go ahead and pull them all the way out so they are out of the way. They like to hang up on the heads and wires when you are trying to coax the covers out.
3. Watch your head cover gasket when you are taking the covers off. One of mine was stuck pretty bad to the head itself and needed some TLC to get it off undamaged. I thought I stretched it pretty good, but it fit back into the groove on the cover without any problem.
4. You will also need to remove the top 2 bolts to the power steering pump and loosen the bottom one. You need to be able to pivot the pump out of the way to get your torque wrench on the cam bolt.
5. Other than that, it is a fun project and also a good time to put that Robertshaw 180 degree thermostat in since you need to drain the coolant to disconnect the heater hoses.
Will let you know results tomorrow when I finish bolting it all back together and take it for a spin.
Fastman also advised me to pull the plugs and turn the motor by hand to make sure none of the valves hit pisons. He doubted it would, but thought safe was better than sorry, and also gives you a chance to check plug wear and see how they look.
