Great post, ill add also with cams need a ported RBC or port matched 72mm RRC.Vit, Let me answer it for you.
Gentlemen the DC2.2 cams Will make more power EVERYWHERE over stock cam because of the duration of the cam. These cams peak at 9200-9500RPM ( that doesnt mean to rev that high.) the Skunk2 Stage 1 cam is a great cam aswell but the peak point of that is 8400-8600 depending on the health of the engine and your mods. The main part of cams is you NEED a flowing header. No replica bullcrap like DC,Strup,PLM. its either a gopower header if you can find one or a skunk2 alpha/megapower
