I have checked to see if water pump was flowing. Dont know how much it flows. But i had this running hot problem with my msd and so i switched to a stock dist with an electronic crane cam pickup. Which seems to work good. It runs great and has a good amount of power buti feel its lacking with all i have done to it. I do have an original cruise o matic in it tho. But even with this new dist same problem. I remember putting in the timing chain and cam and had set it on zero and had two other mechanics double check me. And the balancer.only went on one way.
