YES!!!! it's called TIMING GEARS. Had 'em in my 1966 Pontiac GTO - and in my 1964 Chevy. 'Cept they went away with OH cams. Wonder if it couldn't still be done with an internediate gear???????? Yes... Have you ever seen a Honda VFR750F2 motorcycle engine (among others fer sure)? I has four overhead cams, and a whole bunch of gears in series to make it from the crank up to the cams. NEAT!
