ok when i shut off motor and go quikly into acc position the motor still runs?
if I go from run to off all works good
if i go from run to acc (engine runs) then to off motor turns off.

Your coil curcuit has been wired into the acc circuit. It should only be wired into the run circuit.

MSD TECH support sez:

Try installing the supplied diode in-line on the #4 terminal on the voltage regulator. You can find this in the parts bag for the 6A ignition. If you have switched over to a one wire alternator, install the diode on the main field wire. The unit is seeing residual voltage from the charging system when the key is turned off. For more information on the install, check out pages 8 and 9 of the instruction manual.

funny thing is i took my car into a well know shop that does excellent work on race cars and muscle cars and he switched the wires cuz he said the ign was running off the acc?
maybe he screwed up the wires?

Doc here,

That tech support Information is very good, and would apply IF it didn't shut off at all, in ANY switch position..and certainly worth installing the Diode In case you have that problem in the future...

However, you problem lays on the fact your coil is getting power in both the ACC and RUN positions...To verify this, get a meter or test light, and remove the coil power wire hook up your meter and turn the switch to "RUN" the light will light..or the meter will read 12 volts..next switch it to "OFF" the readings should drop to zero, then to ACC..the readings should read zero here also..I'll bet their reading 12 volts here also, and if that's the case, you need to move the coil power wire to a wire that is HOT IN RUN ONLY..

I would say, the guy switched the wires form "Hot in Run only " to ACC when he said he moved them..Either that..or your Ignition Switch has an internal short in both positions so the "Keyed Circuits" are hot in either position..
