If you aim for a 7000 power level, then you will not have any bottom end. Coupled with that 3.07 rear gear, you will not have any stoplight to stoplight racing because it will take you that long to get the thing going, get into a power curve and get through 1st gear.

Glen, have you ever driven a Honda S2000?

Hi Brent. No, but yes to a Civic with one of those VTEC thingies that rev to the moon, and also considerable miles in a Mazda rotary that had nothing down low, but past that it felt like an electric motor winding up to speed. Could be addictive.
And a V8 with THAT rev range? I remember reading about DL's RCR GT40 from several years ago with - from memory here - a 9.2" deck SBF with an upper limit of around 8000 I think, as well as the ability to drive the kids to the corner shop? OK yes, would have been costly, but what I aspire to is a little less exotic. Brent, I think I have already said that you guys, experts I have absolutely no doubt, have built more engines than I've had hot dinners, but if there's something I think just possibly might be achievable, I shouldn't just rollover as say 'yair, whatever'. If Shelby had said that, we'd all be drivin' them Corvettes now!
Cheers, buddy.
Glen
