Project 505 The Final Chapter
|
3 Since many Mopar cams are designed to work with only 1.50 ratio rocker arms, we worked with Mike Jones at Jones Cam Designs to pick a set of solid-roller camshaft lobes that would work best with our high ratio rocker arms. The camshaft that Mike designed for us was part number R80393-82401. This cam has a fairly mild lobe shape with only .393-inch lobe lift, and a duration of 266 degrees at .050. When combined with the 1.85 rocker arm ratio, this cam profile gave us .707 net-inch lift on the intake side. The exhaust lobes have 272 degrees of duration at .050-inch and lobe lift of .401-inch for a net valve lift of .661 inch. View Related Article
