More like spontaneous acceleration! I once ran a VW beetle with piston rings for a flathead Ford, and wrist pins for a Corvair. J.C. Whitney wouldn't sell me rings- - - - -they wanted me to buy a whole big bore kit when I needed to do a ring job- - - -cylinders, pistons, and all! The connecting rod bushings had enough wear that I needed oversize wrist pins- - - - -Corvair wrist pins were about .015" bigger than the VW pins. Sunnen hone to the rescue!

There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. - Ernest Hemingway
