I have used both of these cams and yes they do run all right on the street, but to just street drive one with newer cams that are available is questionable. They love to drink gas especially in town driving. By the way the older 292 cams from the 70s and the 284 for that matter were made by racer brown. Like I said whatever floats your boat but newer cam designs have as you said 30 years on these models my car runs 4.10s and 25 tall tires so it has plenty of gear and a 2.82 1st 4 spd as well
