If you don't mind going with 915 (1967 440) heads, you can build the motor with quench and pick up some tq/hp to get close to your goal. Another option is KB hyper pistons with a quench dome and use 906 or 452 heads. But the KB / 906 combo may need machine work to get it right. Set piston to head at .040. For pistons, look for a 1/16 1/16 standard oil ring pack. A proper bore and hone with torque plates is the right way to go along with file to fit rings. Set clearances in the bearings for 10w30 weight oil. I would recommend Brad Penn. You will need to get in touch with a good engine builder to come up with where the clearances need to be for that oil. Probably about .0015 to .002 should work. Use a crank scraper or windage tray, and a 1/2 inch pickup and 6 quart pan.
Compression should be set at 9.5 to 1 unless you live at altitude. The 528 cam is a good choice, and the mechanical cam will allow the rpm needed to get to your goal. If you have a choice, go with 1.60 rockers. Some hydraulic combos won't rev well enough. I have seen one that laid over at 5600 rpm. Lastly if you run an automatic trans get a 9.5 converter set to allow some stall, at least 3000 rpm to match that cam.
