The 1969 Hurst/Olds again used the 455-cid V-8 with W-30 heads, cam, distributor, and Force-Air induction. This engine, called the W-46, was slightly detuned from ’68, losing 10 bhp. A H/O modified Turbo Hydra-matic transmission with console-shifted Hurst Dual-Gate was mandatory. As high performance raced into the wacky late ’60s, the idea of a mad scientist conjuring up ever-more-potent 4-4-2s seemed almost reasonable, and Olds advertising was rife with the image of Dr. Oldsmobile in his baggy lab coat and silent-movie mustache. In a sense, there really was such a fellow: Jack “Doc” Watson, head of research for Hurst Performance Products.
