I second that! If you can find the money do it. I just put a new one in and she's very happy. WCB hooked me up with an Isky cam and Crane tappets & rods.

And it will took me a long long time to put it bake together, but I think you know more than I do. How ever long you think it will take x 3.

hmm im considering this, shouldnt you get new lifters as well when you get a new cam? thanks for the input guys.

oh and shop said heads were way over heated, i burned the oil on them, and basically they were very impressed. but they said they would call when they are done of if there is a problem (crack ect.) and i have no call yet, should ge the call tomorrow saying they are done if all goes well.

Where did you take the heads?

Yes, new lifters (tappets) as well.

My D&D cam cam with Crower lifters, but I think they may be the source of my noise (I have heard they were noisy before).

Mine are noisey for about the first 20 seconds of a cold start. After that, I don't hear them.

Those oil pumps go for ever. It's not a bad idea, but I would not sweat it.

X2. The driver and driven gears will last longer than the rest of the truck. The pump body is part of the front cover, and doesn't need to be replaced. What you might consider is just facing the cover plate. You'll need an 8mm box wrench (12 Point) to get the bolts out. The plate surface will likely be scored lightly, but can be lapped with a few sheets of 400 emory paper on a surface plate or other FLAT surface. Just lay the emory on the flat surface and move the plate back and forth till you have lapped all the scoring out of it. A granite kitchen counter makes a good surface plate, just don't get caught. Don't use a piece of wood, not flat or hard enough to do a good job. If you have access to a cast iron surface plate, use valve lapping compound, directly on the surface plate, and skip the emory. Replace the thin paper gasket. There is a feeler guage spec for the gap between the gear faces and the pump body face, using a straight edge, but as long as the bottom plate is lapped clean, you won't do much better. About the only other parts of the pump I'd bother to consider replacing is the relief valve spring and plunger, but not a big deal. There are mixed opinions on packing the pump with vaseline when you put it back together. It does help to pull a prime when starting off with a fresh pump, but frankly I still believe in drill driving the pump for as long as it takes to pull the prime, and I skip the vaseline.
If you are going to replace the cam, refit the new one with some assembly oil, or STP, and be VERY carefull when putting the cam in as cam bearings are very soft and easily scored. Make sure everything is spotlessly clean.
Always replace lifters when replacing a cam. If you're going with a performance cam with extra lift, be sure the lift doesn't exceed the spring compression dimention, and also consider roller rockers.

If you are pulling the oil pump apart, make sure that you mark where the gears meet before letting them fall out. If you do not match them up the same as they came apart you will lose oil pressure as the surfaces have mated together. To will most likely find that if you did not mark them that you will need new gears.

Agree with Terry about using a drill to get the oil through the motor before starting it. Run the drill for around 5 minutes before starting.

thanks guys, if the general concensus is that its tough and doesnt need to be messed with then id much rather leave it alone. right now im deciding if i should leave the bottom end as is and put it back together, or if i should get it honed out and new rings. opinions??? i did get my heads in last friday, here are some before and after pics. they were warped and the shop said they were extremely overheated. burned the oil on them
