RE: Gains?

It would pull to 6k RPM with the stock cam?? When I run at the track I am shifting at 5200 RPM, but I have stock cam, rollers, and heads/intake... Should I be shifting higher in the RPMs?? I have heard of numerous people say that they shift at redline in their stock 5.0 with stock cam, am I doing this wrong? Have also heard of people saying power drops off after 4700, so dont go past 5k at the track.. Would I run better times if I took it to redline??

i installed the trick flow street intake over the summer, and didn't feel a huge differance. i deffinitly got more mid and top end but nothing crazy since i still have the stock heads. with the 1.7's and the underdrive pulleys tho im sure ull feel a very noticable increase. two things about that intake tho... first it makes a whissling noise at idle... everyone told me this was a vacume leak but its not. this is the only intake that does it for some reason. also after i put on the intake i noticed a drop in power after 5,500, and before it would pull right to 6,000. my thoery is that i was getting more air than gas so, this winter i put on an adjustable fuel regulator and cranked up the PSI. ill have to wait till spring to see if i was right... either that or it could be worn valve springs. anyway im sure you'll feel 15-25 hp increase on the top. this will triple with heads tho, remember you have big runners on that new intake but you still have small ports in the heads...
