From his description, he's wanting an engine that will cruise around right off of idle but then make peak horsepower at 7000.
There is a difference between making *some* power at 7000 and making *peak* power at 7000. If you just make *some* power at 7000 and the peak is much lower, then there's no use at all in straining the engine and putting undue stress on it at that rpms. Just because you can see 7000 on a tach doesn't mean that you haven't lost 50-75 hp by the time you get there.
I've given many concrete options for him in previous posts. And again, I'm not trying to be negative, but I'm trying to offer advice that comes from experience.
I agree with you 100%. I think it would be more worthwhile to put the peak down lower, say 6000 rpm, then see how the car behaves that way. If it's not suitable, then parts can be swapped.

Max revs, or change up revs, or 7000, and max power at ....whatever...6500?....
And at the bottom end, able to take 3.08 gearing at 1500prm ideally. That doesn't mean real grunt at 1500, it means at steady speed, level ground, no driveline snatching. If acceleration required, or slight hill encountered, the a change down to third. Oh, and the weight I'm anticipating is 2350lb
Thanks for your continuing interest guys, I though this one might have died a while ago. I AM actually learning stuff here. Appreciated.
Cheers,
