Hard to believe we've gone through September without issuing a single rules tech bulletin...but here we go with the first...
This thread will serve as official notice of CMC Rules changes for the 2016 season. Please do not post replies within this thread. Instead, create new and separate threads for questions/comments on Tech Bulletin updates.
Effective immediately, Ford 302 engines are allowed to be internally balanced by substituting an appropriate aftermarket crankshaft, flywheel, and balancer as long as the combined weight of these three components is at least 73lbs (OEM is 67 by the way) and the flywheel is made of steel. Recommended parts are Scat crank 4-302-3000-5090-2123I, Spec flywheel SF01S and ATI balancer 918921. Carbureted cars employing this modification must run an appropriate aftermarket RPM limiter set to no more than 6,200RPM.
