I've been trying to research building an engine like this. The biggest limiter seems to be valve float. 302-347 will all rev the same these days, though I don't know if the stock block is up to it. It seems easy to find heads that will rev to 6500, but hard to find heads that will rev higher. I see a forged crank and pistons recommended a lot. I've read there are hydraulic lifters that will work, but it may have been a fever dream since everyone recommended solid. Well-balanced internals; and light never hurts...Don't forget that you'll need a transmission that will handle it too (TKX).

The Ferrari 250 Spyder had something like 240hp at 7,000rpm with a 5,000rpm torque peak. The Jaguar E-Types had similar power with a torque peak slightly higher. Those are fun engines, and my car will see a lot more mountains and canyons than stoplights. Some like to feel G-forces from a dig, and some like to wind a smooth engine out for turn after turn, shift after shift.
