Just an off the wall thought for us big guys that have troubles fitting into the 600cc cars. Why doesnt the NMMA adopt the AMA Formula Extreme engine rules. This would allow a greater mix of engines including V-twins. This could create a safer situation for bigger drivers for more leg room, plus some of these engines would be lighter and allow the bigger guys to make weight. Just throwing it out there for some fun ideas. Just think, wouldnt the roar of some big V-twins sound good.
