if it's the new hemi head predator, the standard type clone cam will fit. otherwise, it has to be a cam designed for the predator. the head on the other hand, can be swapped between the clone and the predator which will give it lots more power. trouble is, without a distinct styling or markings, you're not going to be able to tell the difference. you didn't say where you raced, but I have an idea on where and i can tell you now...what's sealed by one can be unsealed by another and you won't be able to tell.....don't let them fool you about tires, tires, tires or that they did thier homework or any other such nonsense....racers are racers and if i can legally or in some cases, illegally, gain an advantage, then i'm going to do it! no...i race a stock appearing class so it's all good, i'm just saying that it's possible to get around seals and wahtever to gain that advantage!! don't for a minute believe that tires are going to put you ahead of the field that fast or that far or that thier setup is any radically different than all the others out there...
anyone that tells you that tires are the secret forget that if you have a junk motor, then all the tires in the world will not make up the difference...same with the greatest motor and a junk set of tires....tires + motor + setup = wins and podium finishes....leave out one of the parts or neglect one part and you ain't nuttin but a back marker racing for last place.
i would be very, very suprised that someone out there doesn't know the secret about getting around the seals and is using it against the field....all it takes is a little paint, the same kind of seals and using your eyes to see how they are sealed....beat that and your on the way to cheating....
not saying anyone is....just that it's entirely possible....
