Gresham Motorsports Park today issued a technical bulletin regarding car weight specifications for those competitors running a McGunegill engine or a 350, 2 barrel V-8 entry in its Pro Late Model Division.

C. The McGunegill Ford # ASA 425LM with 1.5 rockers, 2,775 pounds.

This change reflects a 25-pound reduction of total vehicle weight from the previous 2,800 pound weight requirement for the McGunegill Ford and common 350 2 barrel configurations.
"After studying the segmented lap times of our prior Pro Late Model races here, we felt like this rules change was in order," said Dan Elliott, GMP General Manager. "The competition Chevrolet and Blue Oval engines have made gains as well and this is a good adjustment to make it more competitive. We're always looking at our rules to promote the best competition in each of our divisions. That was the whole point of putting in the seven-loop timing system to begin with. The data provides allows us to look at races after they are over and make the kind of adjustments to the rules when the data will support a reason to."
