Distributor timing curve for 83 SC
 

Can anyone post a timing curve for an 83 SC? All I have are timing values at idle & 6000 rpm. I need the whole curve. I've looked in the archives, but can only find it for previous years...Thanks !

I just went through the timing ordeal on my 83SC. I had it advanced a tad,for what I thought was the correct performance set up.In my case it was not, my 83 seems to run best dead center, I did get better gas milage before I reset it though,I feel that each motor has it own setting, a trial and error thing.

Do you have any more info on the timing curve at different rpm?

Unfortunetaly..... no ! Like I said, I feel that each engine is different, what works for me may not be good for you.Bruce Anderson says in his book timing changes makes little difference
I happen to like the dead center, I tried advancing and noticed some knocking at high rpm's so I set it back a tic, runs really great.I really do not know where to get the info you request,sorry I cannot be of more help. Good luck !
BTW... I have dyno'd my 83SC and get 183hp at the rear wheels
cat by-pass,Bursch muffler,K&N filter and I just turned over 220,000 miles.

The reason I need the whole curve is because I'm replacing my distributor with a programmable electronic ignition system, and right now my engine will only rev to 3000 rpm. Btw my car has *only* 160,000 miles, so I guess I'm still in the break-in period...:D
