Erson Camshaft ...opinion...or whatever
Erson was the stocking cam line at Supershops, hi volume sales. Had a 'Hi-flow 2' in a Cleveland 2V/4V and it ran great. IDK if the cam manufactures are any better than their stock grinds but a custom x/y grind from 1 to anothers x/y grind will be identical. Lost of budding hotrodders back in the 80's first cams were $39 Erson's from Supershops.
