Hi,
I have a mild 440 HP (1971 engine) in my 65 Coronet and was wondering if a step colder plugs than a 85 Autolites would bring down the heat a bit?
Another problem I have is pinging with vacuum advance hooked up and timing set 7° BTDC. Mechanical advance is limited at 19°. Shouldnt be pinging right? Maybe the right plugs can cure it, not sure though.....
Specs:
MSD ready to run
2 1/2 headers
EDE performer
iron heads
680 Quick Fuel vs
+pretty high compression..
THX in advance and all the best from Europe,
Dan
