crank position sensor, how does it work?
How does the crank position sensor on the 96 LT1/LT4's know the position of the crank? Is there something attached to the crank? Do you need a special crank for the 96 ODBII cars?
thanks

The LT5 has a crank sensor it uses notches on the crank... the LT1 & 4 have opti-spark not sure if they have a crank sensor.

The '96 uses a crankshaft reluctor ring that slips over the snout of the crankshaft. The reluctor ring has four "slots" of varying size that are used for positioning.
The reluctor ring is behind the timing cover and is held in place against the crankshaft timing chain gear by the hub. The '96 hub is slightly shorter to allow for the thickness of the reluctor ring.
You do not need a special crank for '96s, other than needing one suitable for use with a one piece rear main seal.

I'm trying to build a 383 motor. I've decieded on a 10.4:1 compression short block from SDPC. Should I have them install the ring or do I pull off the old one from my block and install it. How do I remove it and install it? Just pull it off and push it on? Setting the orientation?

As far as I know, the '96 crankshaft postion sensor is only used for missfire detection by the OBD-II system, and may set a trouble code of not functioning. I don't think it is used by the ECM for any spark or injector timing.
If I remember correctly, I think the '96 has a narrower crank timing-gear to allow space for the reluctor ring and a different timing cover for the sensor.
