This is for a buddy of mine whom im trying to convince to mod. As of right now he has Edelbrock Performer Heads, Powerdyne Blower 9lbs, and a Polished Cobra Intake, B303 cam etc. He runs 12.1's at 118mph. Anyway his car is getting dyno tuned as we speak with a custom chip burned. He is set on a Vortec S Trim, its on the way to the shop. He's contemplating getting Longtube headers, cause now he just has shorties. Also he's thinking of getting a Holley Systemax intake. So in short, how much would long tube headers and a Better intake help him?? Thanks guys!!!
