    Product Description

    Grind # HR-9294-8-CSR

    SBC 377 to 390 CID AFR 190 to 210 Head Max Power 6200 rpm Peak torque 3600. This cam is designed for engines using 3.750” stroke with the AFR Heads and their high Intake the Exhaust flow ratio. This cam maximizes the power potential of these heads by taking advantage of the RAM Effect caused by piston velocity at low rpm. Increase header size of 1.750” is highly suggested to take full advantage of the power band of this camshaft. Adding 1.6 ratio to cam will increase rpm to 6400. We recommend a 3000 stall. We recommend a 850CFM carb and a minimum of 10 to 1.

      Custom cam without the high price

      Posted by Larry Price on 2nd Dec 2016

      I bought this cam to go in my zz383 that I've upgraded with afr heads. This cam is the 3rd roller I've bought. The other 2 were off the shelf from big name cam companies. They all have had the same casting numbers on the cores, but this clay smith cam is the only one that was definitely touched by hand. It has had all the rough edges polished off and had some type of dark coating that the others did not. Came well protected and had no issues during shipping. I wish I had found clay cams years ago, it would have saved me from picking out a off the shelf cam that was not optimal for my engine.
