Inliners International Forums General Discussion Engines difference between 230 and 250

I have a 28,000 mile 230 in my 67 Malibu and a line on a 30,000 mile 230 ($150) to put in my '46 chevy pickup. The 230 for the truck is from a '67 Malibu that was changed into a 396 clone.
Besides 15 hp and 20 ci are there any other differences between these engines?
