As I said I don't plan on going over 7000 with them. On tired springs I wouldn't even try it, but with fresh springs it should be fine. The 284 cam is in the middle of the Schrick range for the M20. The 272 is their street/DD cam, the 284 is the hi-performance street/mild track cam, the 288 cam is for ‘street legal’ track cars, and the 304 is for flat out race cars.
