Magnum 360 rebuild help

My situation is that I purchased a 360 magnum with 70,000 miles on it. I really want to get the car on the road but wondered how far do I need to rebuild the motor to make it reliable. I am planning on running carburetor but feel that if I start by changing the cam it becomes a slippery slope. I would appreciate what advice my fellow a body brothers have.

I bought one with over 90k on it and besides the heads being cracked and being able to see daylight through some of the closed valves :D the bottom end looked great.
So good in fact that I didn't even put new bearings in it, and the cylinders still had really visible cross hatching.
The bottom end looked like it had 10k on it, so I got a set of EQ heads, Roller chain, a cam and new springs and built it as an LA motor.
Doesn't use a drop of oil between changes and runs great.
