Depends on your starter location but most use the 168 teeth FP, you can buy a new Scat SFI part on ebay for around $40.

flexplate response

The only diff in a sbc 400 & 350 flexplate is that a 400 flexplate has weights on it & works in conjunction w/ a 400 harmonic balancer to balance sbc 400 engines.

Since the 383 type motor uses a 400(3.75" stroke) crank to achieve the extra cubes, you need the 400 style flexplate for your motor to be balanced correctly, ... unless, you spent big bucks on an internally balanced crank assembly.
