What exhaust are you running? Even without knowing I'd expect you to see >400rwhp with that combo if everything is functioning properly.
I hope you realized that the springs that come with the AFR205's are not setup for hydraulic roller cams and had them either changed or had ordered them with springs for a hydraulic setup. Unless AFR changed something I'm 90% sure that I'm right on this.
Definitly under 400hp seeing that choking exhaust and the wrong valve springs. Youre running an FTI cam correct? You need the springs Ed recommends or springs that match the valvetrain recommendation on the cam sheet! This thing can easily put out 450hp with the right changes.
I was at 415rwtq with the poopy heads. As to the exhaust, theres alot of guys running cats with big headers. So which makes more power, 1/8 larger diameter tubes with a mid-long tube header OR what I have and no cats..
Man I actually flew home from my second job to see the results!!! Nothing?!?!?!? Hopefully theres so much new power hes just out enjoying it all night.
