The famous 741 cam would be my choice as it's proven over and over again in that cubic inch range. If you wanna wake it up find a good set of 305 to 315 cc aftermarket heads. Not sure what HP your looking for however 600 plus is easily achievable.

Crane 741 cam and Isky 8005 springs would be my choice.
