I have the Scorpions on my 78 Trans Am and am very happy with them. They are very high quality and the price is perfect. So far they have over a year of daily driving use on them with no problems. A lot of people also like the Harland Sharps, but they don't have a lot of material on the top, which to me is just asking for a failure at some point, but to each his own. Unless you're going to run very high spring pressures, any cast aluminum roller rocker will work. The only difference between the Crane and Scorpion rockers is the Cranes are forged aluminum (and overpriced) and the Scorpions are cast aluminum. Whatever you do, don't purchase the Comp Cams roller tip rockers. They are junk and most of the friction is at the fulcrum point, not the tip, so they will give you virtually no gain.
