Tell you what i have that beat a stroked 480... ESR intake is killer, power now, the right jetting, and with your port job you should definitly get a high comp piston. Dynatec ignition and ron woods exhaust

How high of compression are you running? Bump that up if its low. Get your head checked out to see if anythings left in it. Then finally get your carb bored out and possibly a better exhaust...Dasa or Nmotion do the job just fine.

a dyna, otherwise stick with your stocker. programmable is nice if your going to put custom curves on it which i recommend, i did and it was nice, otherwise the non-programable will do
