In 1929, Chevy became a "Six at the Price of Four" by switching to the overhead-valve engine, since lovingly enshrined as the "Stovebolt", because of its large, quarter-inch slotted head bolts. Also sometimes known affectionnately as the "Cast-Iron Wonder", it grew from 194 cid and 50 bhp to 216.5 cid and 85 bhp by 1937, when it was completely redesigned. In 1955, higher compression and internal changes brought the venerable Blue Flame to 123 bhp. |

In their April 94 issue, "Collectible Automobile" magazine selected this motor as one of the American "Ten Best Engines" ever produced: "Simple in the extreme, it set the standard for "Use it and abuse it" reliability that Americans (and Canadians...) still expect in cars". |
