Depends on what you're after, and how you're going to drive it. The original Z28 30-30 production cam and the two much nastier "off-road" cams (which were designed solely for Trans-Am competition, which was constant wide-open throttle between 5000-8000 rpm) were purely "horsepower" cams, as the 302 had very little torque and had to be spun up tight to make power.
What counts in a street engine is TORQUE, not horsepower; there are lots of newer-technology cams out there today that are designed for torque (which is what you want), and which don't require solid lifters. Call your favorite cam grinder, tell them what you expect to do with your car, and they can recommend one that will suit your needs.
