I have an MSD electrical system on my car with an MSD aluminum distributor .

I recently starting having problems with the timming on the engine not staying at the set position and it would advance to high or retard to low while driving the car . I was told by my mechanic that the distributor was sticking in place not allowing the proper advance .

I also noticed the car running hotter at times and my mechanic also told me the distributor not working correctly was most likely causing part of my over heating problem and I needed to change the distributor .

I am not a mechanic so I have to believe what he is telling me .

My question is if I am changing the MSD distributor should I change the MSD 6a box as well since it controls the distributor and could be causing the problem ?

Before I started having problems the temp never moved + or - 2 degrees either way from 180 on the open road or sitting in traffic on hot days . Now sitting at a stop light it will run over 200 . As soon as I start moving again it goes back down to 180 .

I am trying to get this problem corrected so I can drive my car to Pigeon Forge this year .

Any help or advise will be appreciated .
