Did I say that you said that, or not?
I'm comparing apples with oranges? That's rich. I effectively said that F1 engines and Indy Car engines are engineered for different purposes and tolerances, even with the new F1 rules in place which people subsequently mentioned. As such, an F1 car would not (I don't believe) last 300 miles driven at oval speeds and rpm. I really could not give a **** who manufacturers those engines, be it one manufacturer or individual teams. My statement was generic - you chose to take it down the manufacturers route for some reason.
If anybody can give me some proof or explanation that an F1 engine can easily last the distance, at those speeds and rpm, I'm all ears and interested to know.
