I agree that they all *should be* identical, - but that's not always going
to be the case. There are always variables, and just because the same
manufacturer made two (supposedly identical) cams, does not mean that they
are going to all check exactly the same when you put them in your engine.
True, - it is splitting hairs somewhat, - but splitting hairs is what
separates the men from the boys so to speak If it wasn't for splitting
hairs, then everyone who builds identical engines would all make the same
HP and would run the same (and they do not of course).
When you degree a cam in, - you are checking everything that has anything
to do with driving the cam. Changing any part of it should then make it
necessary to check things again.
Shoot, - back when I was drag racing, - I knew guys who checked every LOBE
on a camshaft. I never did that (too much hair splitting for me), - but if
one of these guys happened to swap out a camshaft, and then their engine
slowed down, - at least they didn't have to waste a bunch of time trying out
another cam, - they KNEW the one they had was right (I can think of a couple
of times when I wished *I* had checked every lobe!)

Subject: SD Re: Are all cams the same in this situation?
As long as they come from the same manufacturer, for example all the super
60 cams were made by Competition Cams, so they should be identical. If
you
have an MP S60 cam and replaced it with another that had the same specs
but
was manufactured by, say, Cam Dynamics, then it would need to be degreed
again. But, the MP S60, and the Comp Cams model with the same specs,
should
be identical. So in your case, replacing an old S60 with a new one, all
you need to do is to switch your timing gear and the cam key you already
used when degreeing the present cam, over to the new cam.
Barry
I was wondering if you degreed a cam in correctly and all was fine and
then
had to change the cam because the engine was in the car and it wasn't so
easy
or impossible to dial it in, would a new cam be identical and you could
use the
very same ofset cam key or whatever and expect the same timing? Or is
each
cam different slightly? I was wondering about replacing a super 60 cam
[old]
with a new one.
Thanksl,
