Telling the difference between a HO cam and otherwise?

firing order is easiest way to tell
SO 1-5-4-2-6-3-7-8
HO 1-3-7-2-6-5-4-8
now if your getting a stock cam, as far as i know only 302 HO and 351w got this wiring order for the smallblocks. all aftermarket 5.0/5.8 cams got this firing order also. so if your only worried about getting a cam that will work with all the other componants you should be set. most people wont try to sell a lunati as if it were a regular HO.
