Here's a bit of trivia, since this is the HiPo forum where oddball stuff gets discussed at times. When I bought my crankshaft grinder from King's Crankshaft over in North Carolina, he showed me his "cheater" crankshaft- - - - -it's made from a solid billet of steel that weighs around 250 pounds or so and gets whittled out on a CNC mill. The finished product weighs around 38 pounds, instead of the standard 55 pound 350 crank. The first two cylinders at the front have a standard 350 3.48" stroke. The other three cylinder pairs have a 4" stroke. Since the cylinder volume and/or stroke length is usually measured at the #1 cylinder on a tech inspection, most of the time the extra displacement doesn't get discovered without a full engine disassembly. Like Smokey Yunick used to say- - - -"It ain't cheatin' if ya don't get caught!"
LOL!
