I agree with all of that. Originally when I built the engine I was happy with mid 10's, but most know how it is, you always want to go faster. So I guess I hit my goal, but now want a 10 O car that I drive on the street. As long as it idles at a traffic signal and can be driven 100 miles one way I'm happy. Weekend car only. I have no p steering or brakes. If a cam change is only a 10th it's not worth it to me and I dont want heavy spring pressures either. I use the Indy 400-3 which I believe flows way over 400cfm, do you think a smaller intake like a trick flow would help? The last part are you saying my power is locked in the vert?
