Effective immediately the left side percentage for the GM Street Stock crate engine will be increased to 54%. This will be closely monitored and may be adjusted as necessary with prior notification.

TIRE UPDATE (06/12): The 2017 Speedway 660 Tire Policy set out prior to the season for Street Stock and Sportsman competitors has been suspended until further notice. Feedback from teams has made it clear that the policy put in place for the season does not work and Speedway 660 will be taking this into account when looking at forming a new policy in the future for these divisions. Effective immediately, the allotment number is no more. Tire must be purchased from one of the Maritime tracks and scanned within Speedway 660’s database.

TECH NOTE (UPDATE APRIL 10th/17): The 2017 Speedway 660 Rule UPDATES are now available. The main change is the addition of tire rules for Street Stock, Sportsman and Pro Stock as well as several significant updates to the Pro Stock rules package. Also included are the Sharp Shooter and Bandolero rules (no updates). Please read them carefully and any questions regarding them may be forwarded to the tech director by email at
