saw your cam notes on the pg. there -was- a [paul?] winfield in the early hotrod days. maybe he was a big-time indy mech in the late '60s.
[re: the Navarro motor came with a Sig Erson cam with "WINFIELD" stamped on the end]
Well, this might or might not be a coincidence, but Winfield's cam shop was across the railroad tracks (less than a block) from Navarro's shop!
