Mopar Performance "Purple Shaft Cams" are probally what you are refering to . They are excellent in a high perf. R.B. . If you keep your Adv. Duration below 285 it should be streetable. Part # 312-P4120235 from Jeg's is considered a 3/4 cam profile is 284/284,.484/.484 it should provide descent power.But in the end it,s you that has to decide what you want your motor to do Low torque or high end horsepower or somewhere in between.
