Reply to "Pantera died/won't start -- diagnosis?"

In many Panteras this happens to, the simple cause is a sheared roll pin in the distributor drive gear. Pull the distributor and look through the hole where the pin is. If the pin shears, the rotor doesn't turn, or it can also partially shear so the rotor turns but is 50-100 degrees out of proper time. In another Pantera I fiddled with, the original timing chain was still in there after 30+ years, and it was so worn, the cam jumped proper time by nearly 180 degrees. A 351-C gets approx. 20,000 miles on even the best timing chain (which is NOT a stock silent-chain), due to the heavy weight of the stock valves and the potential rpm capabilities of this engine.
What ignition are you running?
