Did you mean timing gears instead of timing cam or did you mean a full camshaft swap?

If in fact you are going for a full-on cam replacement you're in for a lot of work. It's not hard to do but it is somewhat time consuming. Not only do you have to pull the intake, distributor, valve covers, lifters and pushrods you also have to pull the water pump, harmonic balancer, drop the oil pan and pull the timing cover. You may also have to lift the engine out of the engine mounts with a hoist to allow room to drop the oil pan enough to pull the front cover, this is a good time to replace the oil pan gasket. You're probably also going to have to pull the radiator and maybe even the grille to allow enough room to swap out the cam. If you have air conditioning then you're going to have to pull the condenser and probably the compressor as well. If you do have air conditioning then the refrigerant will be R-12 and it is illegal to vent that stuff to the atmosphere which means you're going to have to pay somebody to recover the refrigerant. Plan for two days to do the job, if you get started Sunday then the chances are pretty good that you won't get it done.

A timing chain replacement won't take nearly as long but you should still plan on dropping the entire oil pan in order to replace the oil pan gasket. You're going to go far enough into the engine that it would be a good time to change it out, especially if it's leaking. Give yourself the entire day for this job just in case you run into any unexpected problems.
