YOu hate HotRod cams? are you sure?
If you wanna play N/A get ready to spend Boku dollars, thats why most people just get blown, because at the end of the day, it will cost the same. However, i think N/A is more reliable and doesnt have heat soak issues when racing.
If you want power your gonna have to shell out the dough for labor and do SPR/VSR cams, my Buddy did Comp Stage 2 SPR and had great results, it doesnt sound as mean as the NSR's but it makes twice the power. He made 340 RWHP on a Mustang Dyno with Long tubes!! tahts about 390 RWHP in Dyno Jet language.
