I filled in the blanks by calculating the missing points from the duration 
and the given points. It certainly looks like the Mag cam is a viable 
replacement for the long ram cam and may even work respectably with short 
rams. The Mag cam beats them both on lift. Dan, do your timing figures 
include the 4 degree retard provided by the timing gears? The timing figures 
for the Long ram cam look like they are 4 degrees retarded as shown. Figures 
for a 4 degree advance are shown in parantheses. I've added the dashes (-) 
the keep the columns aligned during transmission.

BTW, I misquoted the horsepower and torque figures for the 375 horse 440 
(some are mixed up with 6-Pack numbers). They are:
375HP @ 4600RPM and 480lb-ft@3200RPM.

Now, where can I get a Short ram cam for my 440 Mag????
