Ah, yer condemned to be one of us. Those that think to hard. Double check three times and yet still make miss steaks. 
    I condemn you to drink heavily. Or perhaps not. 
    As the saying goes. A day you don't learn something new is wasted!  
     
Today I am learning that what ever my dog ate yesterday gave him a lot of gas...  Now that is a lesson I could do without!

OK, I screwed up. I made three mistakes:

1) Apples vs. oranges, as Bruce pointed out (a man of few but correct words,
I should take the hint)

2) I flubbed cam data entry

but worst

3) I bad-mouthed someone's work (Doug Galvin's cam grinder) before I knew
WTF I was talking about.

I know seat to seat vs. .050 is wrong. I got confused comparing "modern" cam
specs vs. the factory grind. If I was comparing brands A, B, C it would be
easier. I should have just looked at the resulting curves. But the reason
for the bad results in SCDynoSim was that I did not clear all the old cam
data out when I entered the new cam's data; there were some old seat-to-seat
#'s in there (I typed over an old cam and did save-as). When I cleared and
reentered it it all makes sense. The cam looks great now (about 15%
improvement at low speeds, moved the HP peak down to 4000 rpm.)

I truly regret bad mouthing the grinder though. No one remembers kind words
but posterity records all the bad ones! I can take my lumps but I don't want
anyone to read that in the future and think that cam Galvin's sells is no
good. That's entirely my fault.
