Steve,

Thanks for the reply. Yes, this is the info I was able to obtain also. I am
looking for the additional data so I can compare present day cams to the
original when I rebuild. I have called a several cam manufacturers, some of
which claim they absolutely know the numbers, yet none of these agree closely
with each other.
Here are some of the numbers I got:

Duration at .050 (IN, EX), Lobe Separation, Lift (IN, EX)
207,207,115,.489,.489
224,232,114,.481,.490
210,216,114,.481,.490
206,221,115,.481,.490

The other response I got from Ralph (thanks) on this reflector was
214,225,117.5,(.481,.490)

Any other info would be appreciated. When I replace the cam, I want to take
advantage of the 20+ years advance in technology and especially not to take a
step backwards. IOW, a small to moderate increase in hp and torque but still
maintain a fairly smooth (not lopey) idle quality.

Thanks again,
Mark
