Cams for 318's

I may have posted this before from some of my old notes

Mopar is very consistent on how they measure cams
they take the blueprint point of where the clearance ramp meets the acceleration ramp and subtract 4 degrees from the opening side and 4 degrees from the closing side
The height of the clearance ramp therefore makes no difference
Turns out this gives close to .008 but varies
you could do this same drill with Racer Brown or Engle who use .008
The chart is both opening and closing so not perfect for asymetrical cams where the close would be longer than the opening to minimise valve bounce

340 Cam 268 208 closes 66 ABDC 114LCA 60 intensity
DC 268 cam 228 closes 62 ABDC 110LCA 40 intensity
DC 280 cam 238 Closes 66 ABDC 110 LCA 42 intensity
DC 284 Cam 241 Closes 70 ABDC 108 LCA 43 intensity
DC 292 Cam 248 Closes 74 ABDC 108 LCA 44 intensity

for all those that recommend advancing the 340 cam 4 degrees the MP 268 cam gives you a much fatter lobe and you can go to the 280 and close the intake about the same place
I do not see my notes for the DC 260 or 248
