Hello all, after the past months i have been working on some small engine updates. Those updates include a full exhaust from header to knockoff flowmaster muffler, new timing chain, new HEI style distributor. I swapped the LOM due to the advance not working at all after several tests and the timing would flicker from the mark bad. I put in the hei and my 200 was completely different, better acceleration and driveable. I was able to go 70-75 easy with alot left on the freeway. Since making the switch ive used my car maybe 7 times, 2 car shows and several easy country road runs. On all occasions the temp has gone up to overheated and the radiator boiling over....had to stop serveral times to check it out and the oil pressure would come down...guess from the engine being too hot. Also one night at 12am coming from a show had the car shudder until it couldnt drive anymore. Not sure if the carb vapor locked of the plugs got to hot to fire. I know it has to do with the distributor for sure. I have it set between 10-12 degree and its solid....great advance. Do you think the timing is to hot and i should back down? To what? I feel like just going back to the broke LOM just to be able to drive.
