The ONLY difference is the cylinder bore, period, so no other manual is needed.Going from memory I think the 313 is 3.875 bore and the 318 is 3.91" If you want I can look it up for you. Otherwise Cranks, manifolds, cams ,rods, etc etc are identical. DOn DulmaGE P>S>I would have no trouble in boring a 313 to 318 size as there is lots of meat. |
