Mine runs great on regular with no EGR system and the timing at 14 degrees. FWIW, my experiments with the timing have told me that you can get the timing up to about 25 degrees before it starts pinging, but after 14 degrees the power starts to suffer.

My 84 carbed 300 runs good on any grade of fuel, it sucks 87 down like nothing. Runs sweet on 93 octane... best power and economy. I run the 93 octane when doing heavy pulling and 4 wheeling, otherwise I like to stick with at least midgrade 89.
