15 yrs old rebuild 390fe engine that has been running mostly fine for 15 yrs. I pick car up after having some leaks fixed along with fluid change and brake work done recently. As I drove home it had a knock at driving speed. A few days later I drove car and the engine cut out twice for a few seconds each time. When I came to a stop the whole car was shaking like crazy. After checking carb adj. Timing distributor, plugs and wires and finally compression on each cylinder I found cylinder 3 and 4 to have none. Other cylinders were 130ish to 135ish. Old was full but I used a zink type oil this time. What are your thoughts?
