not trying to be constantly argumentative, but........ you don't need much power at 1500 rpm in a lightweight car. A stock Hi-Po flat tappet cam in a 289 K code engine will be quite happy idling at 900 rpm and pull cleanly to the maximum power rpm which is 6000 to 6500 rpm. With just a little head work you can get usable HP beyond 6000 easily, and up to 7000 (or more) is not difficult to achieve.

If the OP wants a 7000 rpm engine, then it seems that once opinions are voiced in the negative, it's would be helpful to set aside any reservations we might have and offer concrete ideas on how he might proceed.

That's why I suggested earlier that he should build a 289 FIA dead-on replica, and then drive the snot out of it. Once he's done that, he will know what, if anything. he will have to change in order to have the car he envisions.
