So I have a 331 mostly set up for a supercharger dished piston and that. No charger yet though. Anyway I set the timing at 12 with the spout out. I put the spout in and thecomp put it up to about 15-16. I get minor pinging If im just crusing along. It's very wery minor pinging I can't see why I would have to run less then 12 degress of timing? I thought maybe I was mistaking the pinging as a slight miss but All the ignition is new? Any opionions on this?
timing guestion/Ya another one sorry

the puter should have added a little more than 4*, in my experience.
need more info: what is your C.R.? octane gas? ambient temps? stuff like that.
first blush, without more info (like when you heard the pinging), i would run 10* static timing and up the octane (again, we need more info - this info is as crude as it gets).
good luck.

When one deletes the EGR, it is best to let the computer know the EGR is gone, as part throttle/cruise detonation can result. to let the computer know, if one is having a chip burned or using a handheld tuner (depends upon the model on the latter), one can turn the EGR off (so the computer knows the EGR is gone).Zero_chance said:
331, i would obviously run the timing down and see how it does. if you cant get rid of it within reason, i would look elsewhere (other than timing) as the cause. there are many things (like faulty EGR) that can cause pinging.
good luck.
