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.

OK, not a truck expert, but Dodge cars offered a 315 poly in 56 and 57 (plus a 315 hemi in 56 and a 325 hemi in 57). 58 Dodge cars' base V8 was a 325 poly. These poly motors were all poly headed versions of the Dodge hemi. 58 was the last year for the Dodge hemi-derived poly motors.

59 Dodge cars' base V8 (in the Coronet) was a one-year-only 326 poly that was a Plymouth 318 poly bored .040 over. Completely different engine than the earlier Dodge poly motors.

I never heard of a Chrysler 315 poly. 56 Chrysler poly motors were 331s, while 57 (and, I think, 58) Chrysler poly motors were 354. These were Chrysler hemi motors with poly heads.

57 was the last year for the Dodge and DeSoto hemis, 58 was the last year for the Chrysler hemi (not counting the 64-71 426 hemis, of course). But Dodge cars still used the Dodge poly motor in 58.

So, I would think a 58 Dodge truck motor would/could be a 315 Dodge poly motor. ????
