Priolo won the 30-lap feature race by more than 10 seconds over Ryan Farrell and Jamie Maiolo in what was the last round of the 2014-15 AHG Sprintcar Series.
Cameron Gessner, who limped over the line with a blown right rear tyre in 12th, claimed enough points to win the series points battle from Jason Kendrick and Priolo.
It was a good night for Priolo who was second quickest in his qualifying group and then took a third and a second in his heat races to qualify for the Silver Dash where he was quick enough to race in the Gold Dash for the right to start on pole.
Priolo belted out a very fast 12.715 second lap in the race against the clock but it was bettered by an even quicker Ryan Farrell who blistered round the track in 12.705 seconds.
The race track was the fastest it has ever been with a handful of drivers powering around in 12-second laps on a track that was well watered thanks to plenty of rain on Friday night and on Saturday before the race meeting.
Farrell lost ground on the start, slipping back to third and Priolo grabbed the holeshot and was extremely fast for the full 30-laps.
Contact between Daniel Harding and Brad Maiolo at the start of the second lap also saw Kye Scroop involved as the cars came together and unfortunately only Scroop was able to get a push away for another start.
By lap five Priolo had a massive lead and he was putting some of his rivals a lap down only seconds later.
Jamie Maiolo was running second when challenged by Farrell who was on his tail by mid-race distance.
The two traded slid jobs and ran side-by-side for a couple of laps before Farrell won the battle and stretched the legs on the #26 machine.
Carl Dowling was very impressive in the #87 entry, starting from P9 and enjoying a couple of midpack battles before edging out Shaun Bradford for fourth in the latter stages.
Bradford managed to finish fifth from Daryl Clayden, Jake Beard-Miller, Troy Lawson, Jason Boland, Lee Nash and Gessner who completed the last two laps up the near fence and out of harm’s way with a shredded right rear tyre.
The win for Priolo was a good result after being so close on quite a few occasions this season, only to blow rear tyres at crucial moments in races.
This time he held on, grabbing the maiden AHG Series win for car owner Rob Watson from Watsons Express Transport.
