undecided on a cam. someone (on here) had priorly suggested 718041-09. RPM range 2300-6000. intake dur at .050 235. ex duration at .050 243. advertized intake duration 289. advertized exhaust duration 297. intake lift .488". exhaust lift .480" lobe seperation 109. it is a 63 dart stock car on a 1/3 mile high banked dirt track. 360/904/5:57 8&3/4. I ain't a cam guy so these are just numbers to me. EDIT that cams' specs say "circle track height rule only", not sure what that means. also a 7K rev limiter is required (tho I dont wanna get anywhere near that) and I almost forgot, the required CR is 9-1 max and will be running EQ heads with the 1.6 ratio
