Yes, the crankshaft is forged, at least on a 235, but it's also got only four main bearings, with the smallest one in the front. The intake ports are siamesed, and the breathing sucks like a Hoover upright vacuum cleaner, so forcing air through them under pressure probably makes some sense, but the connecting rods are long and spindly and subject to bending under the stress a blower engine would put on them. Does the phrase "lipstick on a pig" come to mind? It's sort of like cramming 10 pounds of "fertilizer" (to be forum friendly) in a 5-pound sack- - - -something's going to split, and the result will be a stinky mess!
