Yup, pretty interesting piece of racing history there. With that being said, got to wonder why modern-day Le Mans, Indy, and Formula One cars continue to use OHC engines.

High RPM power, of course. Modern F1 uses 1.6 liter V6 turbo engines, Indy 2.2 liter V6 turbos. Not much low end power to be had with that configuration, so they rev 'em to 12,000 RPM. No pushrod motor will do that.

Agree. The pushrods on an OHV motor would turn into a pretzel at 12,000 rpms--lol!

But at the same time, Chevy engineers get 650 HP and 650 lb-ft of torque out of a pushrod activated small block V8 that passes emissions specs and will run for many thousands of miles, even if the owner has a lead foot.
