That is the old thread that sparked this experiment for historical reference.
Earlier this year I bought and installed a set of Crower stage II cams. I have been using Street Dyno to do a pseudo dyno and see how my changes are affecting my car.
With the crowers I made [email protected] and [email protected]:
I swapped in the stock exhaust cam leaving the crower intake cam and got [email protected] and [email protected]:
Here is an overlay:

Modifications:

Crower stage II cams (noted when replaced with stock)
