Nothing wrong with the high lift cams, they make awesome power as long as the other equipment is right for the application of the cam. But they are still not designed for any kind of extended highway driving. Streetable in every respect but designed for high end horse power. My main point here is not to over cam (+stall converter +low gears, carburetor) a frequently driven vehicle with a camshaft that cant stay at sustained speeds required in usual driving standards. Erson did in fact make some killer high end horse power cams but also had a really nice baseline assortment of cams that were able to stay at sustained speeds and tow with awesome midrange to fair upper end power!
