James and Andy, thanks for that link. Really interesting! That was a lot of power for a little engine, and a lot of races won. And the list of drivers, A. J. Foyt, Dan Gurney, Jimmy Clark, Parnelli Jones, Al and Bobby Unser. It looks like Mario was pretty much unbeatable in '66.
Also, thanks Andy for the heads up on the Olsonite Eagle. I will put that and the Lotus Greg mentioned on my "look for" list.
Yeah, Greg, sometimes what's old is what's new again.
