Treffert was joined on the overall podium in third by American-division winner Alan Sevadjian who stepped into the 1968 No. 37 Duntov Motor Company Corvette roadster regularly driven by his teammate and fellow HSR race winner Clair Schwendeman.

Steve Cullman put in a competitive drive to third overall and second in the American class in his 1970 No. 74 Ford Mustang Boss 302 Trans-Am car prepared by Olthoff Racing.

This year’s featured marque at the 46th HSR Mitty is “The Cars of Japan” and a pair of quick 240Z competitors began the weekend’s celebration with podium finishes in Friday’s Sasco Sports race.


Chris Zappa finished a solid sixth overall and won the International class race in the 1972 No. 44 Datsun 240Z and was joined in victory lane by fellow “Z” car competitor Scott Kissinger, who finished third in his 1971 No. 202 Datsun 240Z.

Rob Albino, another familiar face in Sasco Sports Challenge victory lane, broke up the all 240Z podium in the International division in his Hudson Historics 2000 No. 99 BMW Z3 with a second-place finish.

Friday’s other podium players included Robert Spence who was fifth overall and second in the Porsche class in his 1972 No. 63 Porsche 911 S/T. Craig Watkins completed the Porsche podium in third in his 1968 No. 46 Porsche 911 while Jonathan DeGaynor was third in American and overall in the unique 1960 No. 111 Devin Special.

Saturdays are the biggest day of each year’s Mitty and tomorrow is no exception with several feature races and the first rounds of the weekend’s WeatherTech sprint race doubleheaders.


In addition to the Cars of Japan Feature Race, another can’t miss Saturday sprint is the Third Annual “Gene Felton Memorial Challenge” for HSR Group 8 Historic Stock Cars.

Saturday concludes with the second race of the inaugural HSR Prototype Challenge presented by IMSA series that debuted with a thriller at the Sebring Spring Fling. Saturday’s two-hour race at 6 p.m. EDT will be highlighted by a rematch between the Sebring-winning No. 37 One Motorsports Ligier JS P3 and co-drivers Jon Field and Kenton Koch and Alex Koreiba and James French in the No. 25 Wolf Motorsports Ligier JS P3.
