Realistic expectations

Yeah Sky, it's at 341 right now. I really value your .02, everyone elses too, but I keep getting so many different opinions (I guess that's why I'm so *******' confused). I've heard that 1 5/8 and 2 1/2 set up is all that's needed up to 600 hp, etc, etc. If anyone has more comments, I'd appreciate them, eve if I get more confused and have to rely on an eenie-meenie-minie-mo to pick the parts Thanks for all your comments......keep 'em comin'.
