I had these special made for me by Harland Sharp when he was still alive in the 1970’s. I used to drive hopped up Cadillacs in those days. No one made a performance camshaft for the 472 engines back then, so the only way to get more low end torque was to open the valves early and close them later, thereby adding more duration and fuel charge. It worked.
I used them for a summer so they are still like new. I then switched to Buicks. Buick had the Export Cam and Dual 4’s and Headers and were cheaper to Hot Rod. So these Rockers have been in storage for about 30 to 40 years. I had to have the Rocker Covers heightened because there weren’t any such covers for a Cad Engine back then. These are probably the only Cad 472 Roller Rocker Arms ever made with a 1.75 Ratio. I’m asking $2900.00 for them. They probably cost me the equivalent of double that in the 1970’s.
