1934 Ford Mustang Repair Question
Mileage: No information provided.
342 stroker blowing head gaskets
Answer
I would look carefully at the header on the right side. Insure you have a high quality gasket to conduct heat from the head. Do you have an air dam on the rad cowling to force air on the engine? I think the problem is heat related. Is there good water flow through the head and are you using the new high temp coolant at 50%.
Let me know, I am an old racer from way back.
I have ceramic coated headers, and I am using ford racing header gaskets. I have a Hi flow water pump, and have made sure that the head gasket does not block any of the ports. I am using regular antifreeze with red line water wetter; I have a racing aluminum radiator with two eletric fans. Thanks for your info
You can ask any of the old Ford racing mechanics about water flow. If the water flows too fast through the head it will not cool right. On occasions I had to cut every other impeller from a water pump to slow the water flow.
Go to Napa and buy an infa red Temp gun and check for hot spots on the head. Compare one side with the other.
My last Ford engine was a full race 429 big block stroker and I had a water flow problem on the right head. Those are huge heads over 100 lbs a piece. I went from a hi-flow water pump to a stock Ford pump and it fixed the problem. You have to admit, some thing is wrong and I don't think it is gaskets or the head.
Are you running a t-stat? If not PUT ONE IN! It will modify the water flow so the engine will cool evenly.
Good luck
