Chris mentioned the event at Mid Ohio, and I was there, so I looked up the results.
A 1970 Datsun 240Z (2.8L) took 4th (SVRA Group 8 )
There were a few Datsun 2000 roadsters there too, an the best finish for that was 4th also.
Next year we can make it a club event, and we can get some laps on race-day to show off the cars.
