Everyone running a Zetec engine should be aware of a GCR rule change in August. The minimum weight of cars with a Zetec has been raised to 1220 lbs (from 1200 lbs). As per the Fast Track bulletin, this is to encourage Pinto-powered cars to enter races, even though the CRB recognizes that there is little performance difference between the two engines. So are they handicapping the Zetec cars for no good reason?
