I'm posting the current working draft of the rules underwhich Club Fords will participate in Monoposto vintage events. There are some important things to bear in mind:
1. This is a DRAFT document currently under review and comment. It WILL change before it becomes final.
2. The rules update for vintage FF's currently discusses permitting the recently approved crankshafts by SCCA. This is important since vintage FF's and vintage FF70 Formula Fords (Club Fords) will very likely run to the same engine rules.
3. The draft FF70 rules reference the Monoposto Rules which can viewed at www.monoposto.com
Please bear in mind that these rules are currently undergoing some minor updates, so some of the words can/will change before all this becomes final.
However, I have been getting emails from racers eager to see the FF70 rules, so here is the current draft version:
