"That 270 Offy I'm working on was for Nat Rounds' rear-engine Champ Car. I worked on the chassis after they got it going and after I rebuilt the Offy. I went through it and changed the clearances, had Ed Winfield do the cams. It never made the Indy 500 because it weighed 2,200 pounds ... 400 pounds too heavy. The Offenhauser engines were a complete mystery to the average mechanic in those days. They were accustomed to getting the cylinder heads off of a Flathead V-8 in nothing flat, but with the dual-overhead cam Offenhauser, you had to disassemble it very carefully, take the crankshaft out through the flywheel end, all that stuff. I worked for Emil Diedt (famed Champ Car fabricator) and Lujie Lesovsky (metal shaper extraordinaire) at 53rd and Figueroa in L.A. They were master craftsmen."
