Old School Engine Rebuild
I'd put a windage tray in to help control the oil inside the motor, along with a recurved dist and a performer or stock cast iron 4 bbl intake as mentioned above.
Headers will make a huge difference in power and torque.
I'd get a mild stall converter for it too. Best thing to do is call up the converter companies and tell them your exact combination, they'll tell you what stall converter to use.
