Randy,
As far as cam advance goes all I've seen on dyno is when advanced gain a few pounds tq lose few hp lower peak 100 or 200 rpm ,retard exact opposite lose few# tq gain couple hp raise peaks 100-200 rpm. IMO cam timing changes are better tested on track
my experience with stick cars is advanced cam timing does'nt seem to work well they sound better better response but just don't want to go anywhere,also when you opened lash you lost a little duration and overlap that can tell you some info about your cam,usaully it takes .005 increments to show try tighten intake .005 loosen exhaust.005 from recommened settings if that works I promise you have HP&TQ in cam change PM me if you do I tell you who will fix that cam for you.
Hood Scoops will sure mess with jetting,speaking of jets if useing holley jets DON'T they are not accurate you can change them and get no results or opposite of what you should.
Convert to Max Jet they are precise when you make change you get results.
One other thing dyno numbers are corrected hp &tq., second,do you know for sure #'s are'nt adjusted for desired results. PS manipulated #'s from correction factor usaully gain lots of tq.
