Midwest Dirt Racing League Late Models feature at Portsmouth Raceway Park.
The race was not the typical flag-to-flag win as Conley had someone on his back bumper nearly the entire race.
Tim Dohm was the early pursuer harassing in a dead-heat at the end of lap three.
Dohm stayed close before Josh McGuire picked up the chase and came up beside Conley on a couple of occasions but was turned away.
After starting deep in the pack, Steve Casebolt, Jr. picked up the challenge late in the race with McGuire fading back to fourth.
McGuire put together another charge in the final laps but Conley stayed in front.
As the cars were coming out of the final turn of the 40-lap race, McGuire's car lost power. The cars behind came to the line with cars banging into one another and others spinning.
Dohm squeezed by to finish second and with a bump from behind, McGuire was third.
Rod Conley came through to finish fourth, while Casebolt spun by the flagstand in the infield to finished fifth.
Doug Adkins started at the front of the modified feature and went on to his fifth win in six races this season at PRP.
However, the race was not a typical runaway for Adkins either.
He nearly spun out in turn four of lap one. His recovery cost him valuable position as he fell back to 10th.
After regaining his composure, Adkins began picking off cars that had passed him. Midway through the race Adkins caught up with leader Chuck Yeley and overtook him to maintain the lead for the rest of the race.
Yeley held on to second place for his best-ever PRP feature finish.
John Melvin started on the front row and stormed to his fifth limited late model victory.
With the win, Melvin is undefeated this season at PRP. His most serious challengers ran into trouble.
Jeremie Bretz gained his second PRP bomber feature win.
Bretz jumped to the lead on the drop of the green flag and held off all challenges.
The action continues Saturday with the Bomber Shootout, sponsored by Weaver Gas and Oil.
