Well, to start with the car, it is not the daily driver, it will see the street on the weekends and I don't plan on every taking it out on long road trips unless to the track which is only about 50 miles from where I live.
I just recieved the new gears today and I'm waiting on an order for new tires to help hook when I go back to the track this fall. So if I lost a little low end torque It might not be the end of the world, but I guess solid gains across the chart would be nice while droping a few tenths.
I don't like the idea of losing power until 5000rpm. Hoping to hit at least mid 12 n/a would really make me happy though I know I need to see where I'm at now to know how far I need to go.
I've ran the 1/4 mile 2 years ago all stock at 14.1. I've never had the time/or made the time to go back out there after mods. So before I do any engine work I'm going to install the new gears and get some practice out their to see what I can do now. Hope that helps
Well. If i understand your response correctly, I would say your looking for a cam that provides midrange to high end punch. If your going steep gears, the low end loss will NOT be a big issue. Below are some CAMS that I was originally interested in. (and dont believe their power claims)

If you want to go a little more aggressive, Hensler has a custom grind CAM that helped to produce 380+ rwhp on a big bore NA engine (and that was before breakin). Below is an attachment to my webpage that has my build specs and there is a link to hensler racing near the bottom. Talk to James. He can give you his suggestions & he knows what he's talking about.
