You need a 400" crank which is a 3.85" stroke. :imo

Piston compression height changes when you "stroke" the motor, rod length typically changes, you'll have to notch the block in a few places for the rods to clear.

383 uses the stock 350 bore and a crank from a 400 so with yours being .030 over it'd be about 388. Plus all the other parts Hit Man mentioned. It should give a nice torque increase.
