Any advise would be appreciated. I have been having alittle problem with pinging. I have played with the timing and added octane boost. I am running 10.5 to 10.8 compression with a comp 280h cam. I have talked to several people running this compression on pump gas without pinging, but I still get it alittle on WOT. I am thinking that if I upgrade to all MSD it might help. Also, would the plug gap be an issue or bigger wires. I am at .35 with autolite 45's and standard wires. Thanks for the help.
