58 dodge d100 315 poly
First thing. Where do you come up with the 315 Poly? A D100 from 58 to 65 should of had a 313 with a 3 7/8 bore. A Chrysler from 57 to 65 could be a 313 also. A 315 really is a 1 year only offering for a 56 Chrysler. Anyway, lets continue. What is the "register" diameter of the butt end of that crank, where a torque converter snout would engage? This may be your only concern.
