sbc 350 distributor will not sit properly on oil pump shaft

I have a 350 converted into a 383 stroker. It was running fun until I broke a rocker arm stud. After buying new cylinder heads (70cc Aluminum Edledbrok performer head) I was not able to put the distributor back in place. It sits maybe a half inch higher than were it should. I have tried everything I can think of to get it to sit back in place but it simply wont go in. I heard I can pull the oil pump shaft out but I am not totally sure how to do so. Could I just lift it out buy using a magnet? Will the same problem occur when I put it back into place? Any help will be greatly appreciated, I am starting to run out of time.

You cannot pull it out from the top. You have to phase it. Is the number one cylinder on TDC? if not make it so, then pull the cap off the dizzy. I like to place my timing mark on the balancer about 12 degrees BTDC then point the rotor toward the #1 cylinder. then using a long screw driver or tire iron turn the oil pump to line up with the distributor. Remember the gear will turn your rotor so you'll have to turn it back some so it comes around and falls in the slot.

You can't feel it go in the slot at all? Does the oil pump spinn freely?

It will go into the slot fine if we take the gears off the distributor but with the gears on it doesn't sit in the slot at all.

Well without seeing it I'm not sure what to tell you. Your sure the slot is lining up with the oil pump shaft? Sounds like your just a tooth or two off.

This further supports the fact that the oil pump shaft needs to be rotated slightly so that the notch lines up, taking the helix of the gear into consideration. It may be a "trial and error" situation getting it to drop into place.

Do NOT bump the engine with the starter in an attempt to get it to drop into place, or risk cam gear damage. (Not fun!)

Gently rotating the rotor within the range of the advance springs may do it if it's very close?

If you have had the gear off the distributor.....it sounds like you have reinstalled it upside down.
