Tom, thanks for the memories
I remember reading about the Plymouth motorcycle in an old Popular Mechanix
mag---Grandma's basement included a treasure trove of those old 1930s mags
(leftover by my uncles ), so in the late 1940s I was able to read 1930s land
speed coverage in the original articles. There was also an article about a
boat racer, based in Philadelphia, who ran a Plymouth 6 with triple carbs on
a home made manifold made out of exhaust tubing with wheel bearing dust caps
as the manifold end caps. He ported and relieved the block and ran a wild
cam up to 7000 RPM (this was in the 1940s, wonder who he was?)
Was inspired to build my first engine, a Plymouth 6, as a result, used an
aftermarket aluminum high compression head and dual carb manifold, 3/4 cam
and put it in a 1934 Plymouth--was fast for those early days and with the
early independent front suspension handled well. My mistake was relieving
the block (following the boat racer's lead) but that lowered the compression
and unlike the Ford flatheads, the valve stems were parallel with the
cylinder bore, so it probably didn't improve breathing all that much.
