Well Tha casting numbers have been known to go both ways(230/250) And The only way to tell them apart then Is to look at the Head of the piston.So it is easy to make a 230 out of a 250 Just use all the 230 parts crank rods pistons. But whenUseing the crank from the 230 (well this goes for any motor Not useing the stock Crank from which it came) it is a good idea to have the Crank Line bore Checked TO make sure the crank spins freely. Hope this helps }[oooooo]
