340cui with .070 bore

If its a 4" stroke crank with a .070" over bore you'll have 425 cubes. A 412 would be a 4" crank with a .010" over bore.

i think the 340 with a 4" crank is 416 with the standard bore alone. the 360 comes out to 406 with the standard 4" bore and the 4" stroke. so the 340 .010 over should be more than 412
