Flandy.... You're scaring me!!! 11:1 slugs and 38 degrees of timing on regular????? THAT is scary. I hope you have good ears. I'm damn near deaf and wouldn't dare.

I agree, my stock 77 also pings on regular gas. It also pings some on mid-grade & none at all on 93 octane.

Vette(s): 74 mille miglia red 454 auto. Zora's favorite!
My 74 loves regular. Admittedly it's a LS4, but it runs like a top, will set the tires afire, and doesn't ping at all.
 
Interestingly, my 73 Monte and Elky LS4s BOTH hate regular, and they have the same timing, carburetion, etc. as my Vette.
