Why did I say two-wheeler? Oh well, it was 2.5yrs ago.



It was interesting to see the shrouding of half of each valve, and the trade-off between breathing and compression ratio.

Hotrodders relied on the junkyards being full of obsolete flatheads and GMC 6-71 superchargers. That combination breathes as well as a naturally aspirated overhead valve V-8.

There's also the sage of the french military flathead.
