Reluctor Wheel spinning on Crankshaft
A friend of mine just got his Engine together and the Reluctor is spinning on the Crank. It has thrown the car out of time already, we are about to pull the Crank out. We have the Oil Pan off so we know this is the problem.
Does anyone have a diagram to re-align the Reluctor?
It's a Gen III 24x Crank.

I believe there is a GM tool required to install them in the correct position. You will have to pull the crank out of the motor and take it to a machine shop with the correct equipment.

Indexing the 24X Reluctor Wheel
Looking down at the flywheel flange on the crank, there is a dowel hole between two of the six holes (assuming that you don't have one of the new 8-hole cranks). Call this the 12:00c position. The second holes down to the left and right, we'll call 9:00c & 3:00c respectively.
The side of the reluctor wheel facing you should have five large round holes (towards the lower half of the wheel) and a small (~8mm) indexing hole just to the right of the five large holes and two more holes (with a pyramid-shaped top) spaced 180* apart, at 9:00w & 3:00w if you will.
The alignment is to match the center of the 9:00 & 3:00 holes in the crank with the peaks of the pyramids of the 9:00 & 3:00 holes in the reluctor wheel (as in 9:00c to 9:00w and 3:00c to 3:00w).
I have a Goodson tool and the above routine is exactly what the tool duplicates/confirms.
Heat the new reluctor in the oven to ~475* and it will almost fall onto a cooled crank. You may have to reheat the reluctor slightly with a torch if your wife won't let you bring the crank into the kitchen. (Hint: don't let her see you using her insulated oven gloves to hold the reluctor wheel)
