Many are familiar with Hank Bechtloff---'Hank the Crank'. I had an extended discussion with him several years ago regarding the use of aluminium rods in 'street' motors. He told me, among other things, that he was building engines for a fleet of tanker trucks hauling oil in the 'hilly' part of Texas. To get the necessary torque, he was stroking the 460 engines the trucks came with. He didn't go into why he was doing so, but these 'work-horse' engines were being equipped with aluminium rods. He said, "Just put 'em in and drive 'em."
Due in part to this conversation, the turbo'd, sprayed, methanol fueled Jag AJ27 engine going in my daily-driver/ECTA record holder Lincoln LS is equipped with GRP aluminium rods that are based on one of their Pro Stock designs. I may very well pull the engine at the end of the racing season and give the rods a good look, but I DO intend to "drive 'em".
