Constantino charged to the front from his third starting spot, grabbed the lead from Jim Introne Jr. on the third lap and with the race running caution free, lapped up to the third-place car by the end of the 30 lap main event.
Cliff Haslun picked up his third-straight victory in the Street Stock division, while Ivan Joslin won the Pro Stock main event and P.J. Bleau grabbed his second win of the season in the 4-cylinder mini stock class.
Ryan Heath celebrated his first career feature win in the Limited Sportsman division, while Mike Hill won the All-Star Senior Slingshot main event for the fifth time this year and Garrett Poland grabbed his fourth win of the season in the Junior Slingshot class.
Introne showed the Crate Modified field the fast way around the speedway for the first two laps of the 30-lap main event before Constantino and Tim Hartman Jr., who won the last two modified feature, got by on the low side.
While Constantino and Hartman pulled away from the pack, Introne, Billy August, Joe Orlando and Leo Fotopoulos locked in a battle for third.
August broke out of the pack on lap seven, but without the aide of a caution could not close ground on the front runners, as Constantino had him in his sights to be lapped before the checkers flew.
Hartman was second followed by August, Introne, Fotopoulos, Orlando, Don Bellen, Mike Bellinger and Dave Richer.
Joslin got to the front early from his third starting spot in the 20-lap Pro Stock feature and survived a series of early-race restarts to post his second win of the season.
Jim Normoyle made a late-race move to get second,while defending track champion Luke Horning rallied from a lap four spin that put him to the back of the pack to finish third. Justin Knight was fourth followed by Ron Delease, Malcolm Warner, Harley Shepard and Jamie Warner.
Heath made the most of his front row starting spot to grab the early lead in the Limited Sportsman feature and won the race-long battle with Greg Perron to pick up the first feature win of his career. Perron was second followed by Derrick McGrew jr., Shane Larman, Kathy Bellen, Jerry Cohn and Jeff Proctor.
Andy Graves led the opening two laps of the Mini stock feature before Bleau took command on a lap three restart. Graves stayed within striking distance of Bleau until being sidelined with mechanical problems, while under caution on lap 15. The caution was for hard contact with the second turn wall by C.J. Shepler after Chris Andrew’s car faltered and brushed Shepler, sending him with his rear wheels on top of the wall..
John Napoli inherited the runner-up spot but could not chase down Bleau before the checkers flew. Wayne Russell Jr. was the first single-cam Mini Stock across the line in third, while Jim Daniels was fourth, T.J. Marlitt fifth and Dale VanAllen sixth.
