High compression blues.

doubt you can find it easily in california but converting your carburetor to E85 would solve all your issues i run 11.5 to one compression on a 505 wedge with aluminum heads with no pinging whatsoever, honestly i only chose to go with it because i didnt want to chance detonation issues running 91, as well as having to cut back on ignition timing, basically didnt want to be forced to hold back my motor from what it really wants just a suggestion as im not sure e85 is widely available in cali
