Trying to get the timing adjusted on my 73 Charger. Looking for a starting point. I presently have it set at 18 initial and 35 total and it seems dead under 4500 rpms. Its a 470 stroker build with a hughes cam (seh3236bl-10) .571 intake .582 exhaust .236 duration and 110 lobe separation. It has a 750 vac secondary carb. 4 Speed car. Also when setting the idle mixture screw it will die if I screw them both in al the way but will not die if I screw them all the way out (really no change as I screw them out). Any help is greatly appreciated..
