Cyrano, I met Lance and his Chief Mechanic at the sports car races on the Gardnerville-Minden Airport in 1961. I was a lowly course Marshall. He was gracious and friendly. I drooled over his Corvettes. I asked the Chief Mechanic what some of his engine building 'secrets' were. He said that they knurled the pistons and then pounded them into the cylinders, then removed them and installed the rings. Then they use very light weight synthetic oil with very little break-in before the race. He said each engine was used for one race only before doing all that over again.
I don't believe that I ever read anything about his copy-writing the "Scarab" name. The subject never came up while we talked. I do know that even after being raised in LV and living in Reno for years, I never ever saw 'hotter' pit Dollies than those hanging around Lance's operation.
