Hi,

I found this on the Triumph 2000/2500 web site (good stuff there, BTW)

Make          Lift    Timing      Ad  Ol  Dur  Band         Bhp
2.5S          .330''  10/50 50/10  0  20  240  1500-4800    118

I think this is the correct spec.

Bottom line: it's kind of a "wimpy" cam, no offense meant.

Also note that the lift is lift at the valve, not the cam. Multiply .330 by
.7 (more or less) to get the lift at the cam (if you care). Measuring the
cam lobes would confirm that this number is correct. The later cams have a
whopping .340 lift at the valve.

Now, a Triumph Tune Super Sprint... or a Piper 285 - them's got some lift!
