The rules you posted are "Gulfcoast Predator stock Engine Rules". They were written by Randy Schotts of Thunderbolt racing engines back in 2018. The set you have there is literally what I took and put to print using the hand written set he sent me. There are two things that need to be changed...
1. The .488 no-go is now used on all the predator carbs.
2. The Big header and muffler should read
B91-XL. I'm not sure how that typo occurred.
Those rules are accepted at Square County in Lena Ms, Greens Creek Speedway in Prentiss ms, Jackson Motorkart Speedway in Byram Ms. And Mojave Karting Complex in Sterlington LA. They are also being used in the Maximillion touring series that will be racing at Talledega Short track this weekend.
If you have any questions about the legality of any parts feel free to give me a call (601-503-3502). If your need advice on the build itself and making the best power, I'm not the one to help there. I just tear them apart and make sure they have the right parts in them.
