I had the same thing happen with cammotion, and made the mistake of telling them it was driven on the street. Needless to say I pulled that cam out, slapped in an "off the shelf" used $150 (eBay) N-91 and the thing picked up 3 tenths and 3mph with very little track tuning. That being said, although that N-41 is a good cam, I think Jay or Ed could do you up a much better one.
btw, the cam doctor is not for him to tell you what you need, its for him to run a cam and check the exact actual specs of it
