Unlike some people here that seem to be professional forum advisors, I can say without all the BS that you need to start by fixing the distributor. Lock it out. The rest will come easy.
This is where to start. You are not he first guy to build a SBC or use that cam in a SBC.
6 days and 5 pages later and you have not fixed your car yet.
its about 10 minutes work.
You engine is lazy at low rpm because the timing curve is wrong for the cam.
The thing needs a ton of advance at idle. Don't need to know anything else about it to know this.
Don't need to write a book about it.
Fix the stupid distributor.
This is not rocket science. There is nothing wrong with your combo.
