plenty of failures on cammed cars because of people using regular full synthetic. You need ZRod. track club dont you remember all the cammed ls motors that were blowing up because they were using mobile 1. GM says 15w40 is fine for track use so 10w30 is fine for everyday use. With a cam you should be letting the car warm up befor romping on it so the oils going to act like 30w the same as 5w30. if your going to be driving the car in below freezing temps you should put 5w30 in it. people have been running ZRod and Driven for over 100,000 miles and it never clogged a cat. maybe in 200,000 miles it might
