Welcome to the group!  You've got the BEST  "overall"  street engine ever 
made!! imo!  That's why!

You should be able to run solid 87 octane..and never ping....8.75 to 1 
Compression ratio!

Most of us out west have always been able to run 16 BTDC with the stock 
distributor.....why the 6 deg. from GM???  who knows..
