So pretty much any chassis/engine combo from the past 25 years would have a legitimate shot at making the race and being competitive

And how many would pass the current safety regulations?

Now if you were to pull the regulations back 25 years the Penske push-rod M/B probably wouldn't even make the starting grid as technology has advanced so much that laps in the 250 MPH + range (and the ensuing chaos it would cause) would be easily attainable.
