Detonation

Another tech question for the list.

I have started noticing my engine detonating badly as I approach 5000
rpm. This is a serious problem that will keep me off the track this
weekend. So instead I will be spending Saturday in the driveway
trying to isolate the culprit. I plan on doing the following, so if
ya'll can think of anything else to try or look for please let me
know.

1. Check all the plugs and plug wires.
2. Check rotor and distributor cap, (there only about 6 months old).
3. Disconnect my MSD and switch back to the stock coil.
4. Check fuel presure
5. I plan on reading up on adjusting the distributor position in the
    Haynes manuel, and then try playing around with it.
6. I guess I could try a lower temp thermostat, but the engine is not
    getting hot.

Maybe some of our Supercharged members have run into this before???

Anyway any help would be appriciated.
