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!
