Why is it so hard to get good advice !!???

Is this a running motor? If so.. What is it running like ? Is it detonating?
What seems to be the problem ?

I'm sorry if I wasn't clear before. I have posted about this problem in a few forums so I have forgotten what I mentioned.
The engine has about 2500 miles on it since Feb 2011 when I had it out to deglaze the cylinders and put in new rings and bearings.

The engine makes decent power. It idles okay and has no hiccups or stumbling. Its just that I cannot run more than 31 degrees total timing without hearing detonation. Anything past 1/2 throttle and I'll get pinging. I have the distributor set to 17 degrees initial, 31 total and NO vacuum advance. MP electronic distributor and a Chrome box ECU. I can get the car to full throttle without pinging if I use some 110 octane race fuel, but to me that seems like a cop out. I want it to run on pump premium without detonation. Limiting the timing seems like I am cheating myself out of power. The way the car ran, I just KNEW that the combination was mismatched and that there was MORE power to be found. The 292/509 cam was picked by me because in 2004 when I first assembled the engine, Mopar Performance has a crate 500 engine that also used the '509 cam. I thought I was making a safe choice. I later learned that the MP engine was built on 9.5 compression and the '509 cam worked well with it. My higher static compression ratio is obviously not right for that cam.
Learning the cranking compression numbers and now the Dynamic ratio have really cleared things up. Sometimes it takes cold, hard facts to get me to understand.
