Crane 168731 or 168741 cam.
Comp 929 springs GM lifters should work What intake? Can't tell 100% by the pic. |
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.

A cleanup on the heads and a larger intake valve will help with the cam upgrade. The 2.19 valve is small for a 502 bore.

the heads really are holding it back,a set of engine quest heads and a crane 741 cam will get you 600 hp with 9.5 to 1 c/r.
