What is a "stage 2" camshaft? I've heard this terminology before and I know there are a few (not many) who use this terminology in the domestic realm but I always thought it was too vague.
For example Trick Flow made three "stages" of camshafts for the 302. TFS1, TFS2, TFS3. All three are "wilder" than stock, with progressively more aggressive profiles the higher you move up.
However, there are thousands of different combinations of lobe profiles, ramp rates, duration, lift....etc that will yield vastly different results depending on the combination. A boosted application often benefits from negative overlap and exhaust bias for example (in many applications).
So while companies like Trickflow "dumb it down" by offering three "stages" of cams for the 302, you are almost universally better served by going to with a cam from Comp if you want something OTS, or getting one spec'd by a cam grinder for your specific application.
The cam I had ground for my 302 had negative overlap, relatively high lift for a street motor (550+) but was rather tame on the duration front.
Does somebody make a specific set of cams for the group of parts you are putting together by chance?
