RE: Cams

abe,

no problem w/errors - surely, you don't think i never make any?!?  i believe the
lobes are symmetric, but i'm not sure.  still, the total ramp-up/ramp-down would
be the same degree quantity.  i'm currently www-challenged, so i can't help you
w/the crane cams info - i honestly wonder if i could help, even w/the www!
however, there's a cam co. in co that mite be able to help you - they do usa
stuff, i dunno if they do furrin stuff.  here's someone's rxn from the pantera
digest:

Cam Research in Colorado (303.762.8196) ground a customer cam and
matched the head components for me based on my parts (4V quench heads,
headers, etc.) and desires (good streetable HP and tourque, good
vaccum, etc.).  They also broke in the cam.  

I'm very pleased and the extra money was worth it.  Also, be sure that
everything is matched (pistons, cam,  port plates, etc.) and BALANCED.
 My motor was 4 oz. off at the rear of the crank.  What a DIFFERENCE!


good luck,

doug s.

	The 225 was a typo.  After I sent the e-mail last night I came up with
the
	same logic as you stated in your e-mail today.  However I was not sure
if
	the rise and fall of the lobe is symmetrical.  If it is indeed
symmetrical,
	then your/my logic is correct.  But if it is not, then the 50-50 spilt
of
	the difference between the duration at 0 lift and .050 lift is not
correct.

	I am still a rookie at this cam business, so if I am way off please
correct
	me no offense.

	The numbers you provided are correct according to the shop manual and
also
	as given by a document at Centerline Alfa http://www.centerlinealfa.com/
	<http://www.centerlinealfa.com/>  under Tips and Techniques.

	What I am looking for is information such as given in item K in this
example
	http://www.cranecams.com/spechowto.htm

	Thanks again for your help.
