Engine Performance problem
1977 Other Dodge Models V8 Two Wheel Drive Automatic 25000 miles
Hi, My 1977 RV dodge 440 engine is pinging really bad after it warms up (about 10 miles). I lose power and can barely go up a small incline or over 40 mph on the freeway.
The rebuilt engine has 25,000 miles. The Edlebrock carb was rebuilt and adjusted. All vacuum lines checked. Timing was in spec at 7.5-8 TDC. Vacuum advance is moving. Spark plugs and wires changed. Tried various unleaded gasoline brands, tried octane booster. Changed gas filter.
None of the above has made any difference. Can you give me some clues on what else might be causing the problem? It obvious now that it is not an obvious problem.
Thank you for all suggestions or anything I can try to zero in on the problem.
