We popped two engines this weekend because of downshifts without braking, or downshifting to early, both cars broke the intake cam so those of you that are going to do sealed engine rebuilds, make sure your car has a pinned cam or get one during your rebuild, it pays off believe me, I has up until 1130 Saturday changing engines and the race ended at 3:30 that afternoon...do yourself a favor and don't scrimp on the engine extras.
