What kind of distributor is it? Do you have a dial back light or degreed balancer?

With that cam you want about 20-24 degrees initial timing and 34-40 degrees total. Most stock Chrysler distributors have about 22-24 degrees of advance in them.
iagree
Does the motor start and idle okay?
Ignition timing can make a motor perform well or not, it depends on several things like which compression ratio, what quality of fuel being used, which spark plug and a few other things.
Start with the basics first, figure out what you have now and let us know so we can "school" help you on how to make it the best it can be scope
Let us know what you find, BTW that 750 carb.ain't big enough for a mild 440, let alone future growth work shruggy
