Finding one of those engines in rebuildable shape would be difficult at best. They also came in a 250 CID version with a Quadrejet carb. That Q-jet is about as scarce as a chicken with lips, and priced accordingly. Sort of like the dual overhead cam Cosworth Vega engine, the lower end of the 230 and 250 engines didn't like the extra grunt the OHC head could produce. A good hotrod buildup of a pushrod 250 with some skillful cylinder head work would probably leave the OHC Pontiac in the dust, and those engines are cheap and plentiful. I'm considering doing a buildup of a 230 pushrod engine (shorter stroke) with a roller cam, NASCAR tool steel connecting rods, and 3 side draft motorcycle carburetors that will live happily in the 7K RPM range or higher. Like most hotrod projects "There's no substitute for cubic dollars!"
