Ok so I'm doing a heads/cam/intake swap and its time to start putting it all back together..I bought a new oil pump because of the high milage and people told me I have to center the pump...how in the worl do I do that it has 4 bolts and bolts up any advice would be great as I'm totally lost I've never done that w/past cars.

"They" are probably talking about aligning the gears up.
Here is a old write up........

__________________________________________________ ______________
Find your oil pump pickup tube O-ring, it may be brown or blue in color. It will either be inside the opening of your stock oil pump, or it'll still be on the snout of the pickup tube. If it was inside the oil pump, remove it and place it on the snout of the pickup tube...just seat it on there, don't force it down any more than it wants to go naturally.

If you bought a new oil pump, get it out now and place your old pump aside. Now, push the pickup tube downwards with one hand, and with the other, try to line up the gear on the oil pump with the gear on the crankshaft and push it on. Again, this may take a few minutes to get the gears all lined up. Once the pump slides on, rotate it a little and try to line up the snout so it'll slip into the oil pump nice and centered. If you try to insert it off center, you run the risk of chewing up the o-ring which will mean you have very little oil pressure and have to tear all this apart to get back in here to replace it. You don't want that, so make sure you insert the pickup tube nice and centered. It shouldn't take much force at all to push it in. Once it's in, apply Loctite® to the old pickup tube bolt and re-install it. The torque specs are about 9 lb/ft, so just tighten it with a small wrench so it's snug but don't go crazy on it, as it's a really small bolt and the threads will strip out with too much force.

Apply Loctite® to the 4 10mm oil pump bolts and reinstall them, torqueing them to 18 lb/ft.

Now, retighten up the oil pan bolts. The smaller bolts get torqued to 106 INCH lbs, or about 9 foot lbs, while the bigger bolts get torqued to 18 lb/ft. Note: You WILL break those smaller headed bolts if you go past the 9 lb/ft as specified.

Sarge is right! And getting a new oil pump if your car has miles is the right way to do it

I put 3 separte feeler gauges(.003 ish) in between crank & oil pump gears...just to be sure the pump was centered on the crack shaft

that pick up tube bolt will be much easier with the engine out.....I didn't center anything when I did mine I don't believe. Just watch the o-ring.......easy to pinch and ruin that if you're not careful.
