i have a 59 chevy pickup with a 235 in need of an overhaul& have found a rebuilt 230 from a 65 chevy truck for next to nothing.would this engine bolt right up & if not what changes would have to be made.power wise how do the 2 compare.i have visited this site over the last few month since i bought this truck & you guys have inspired me to not do as was planned which was to swap out the old 235 for a 350.thanks in advance for the help i know will be coming.
