obd1 vs obd2 crank/crank timing gear differences?

[stormy69]

I bought an obd1 motor that ran good and after a head job (port/polish and valve grind) and a cam I am almost ready to install it in my sons 97 formula. I had forgotten about the hall effect trigger for the CPS and am hoping somebody will verify it will work in/on an obd1 motor/crank. Is the crank gear different 1 vs 2?

His old motor is going in my daughters 94 z28 when i get the head work finished on it.

As you can see, we are making some big changes!
