Ignition timing 347

hi i have a 89 foxbody stroked to a 347 10.1 compression using gt40 heads and 2.02 and 1.60 valves and shorty headers and cobra intake and 26lb fuel injectors and i was wondering what is the best and most timing i can get out of my ignition without any harm and the most power.

Re: Ignition timing 347

I would think 34-36 total timing would net you the most power. You might get more, but it all depends on your fuel octane your using as well.

347 Stroker, 10.6:1, Vic Jr, World Jr. heads (2.02/1.60 valves), Custom 780cfm ProSystems 4150 Double Pumper, XE284H cam, MSD E-Curve, 4.30 gears/31 Spline axles, Tremec TKO 5 Speed w/.83 5th gear ratio.

Re: Ignition timing 347

Is that the stock computer or do you have a 'tune' in it via "tweecer" or a "chip".?
