If you pulled your dizzy out and didn't re-phase it exactly, then you might have set a high base ignition advance which would explain the pinging. Get a timing light and set the base timing. On the stock ECU, you have to short two pins together on the diagnostic connector to force the ECU fire at what it thinks is 10 degrees BTDC. Adjust your dizzy until the timing light shows 10 BTDC.
You might also have a manifold leak which could cause the RPM to go high. Ignition advance alone would only get you a few hundred RPM increase, so it sounds like you have air bypassing your throttle too. If the air bypasses your AFM (assuming yours is AFM), then you will get lean mixtures too which also leads to pinging.
Hope this helps.
