Timing chain jumped? Pull #1 spark plug. With a helper bump the starter til your finger is blown off the empty spark plug hole. You will be at TDC. Remove the dust cap and see if the rotor is pointing at the #1 plug wire. If not, the chain probably jumped or you missed the set up when you replaced the distributor. Good luck.🛠
