Yes, I changed radiators out.. Truck sat for a couple weeks and dead battery. Went to jump the truck and no fire, put battery charger on for most of the day. Coil tested ok with spark going to distributor, but no spark at plugs. So it has something to do with distributor.. Right?

Pull the distributor cap off and the rotor is not spinning when trying to crank truck, means probably timing chain.. Right? Cause the gear on the distro shaft seems fine.

Pulled off front end of motor and timing chain is good...what now?

Make sure the teeth on the cam are good. Did you turn the crank and watch the cam turn with the timing cover off? Make sure the roll pin is present holding the gear on the dizzy shaft.

Crank turns timing chain, timing chain turns cam, cam turns dizzy. Must be one of the three.

Found the problem... Then sheer pin between the timing chain and the cam had walked itself out and was not connected.. Push back into place and lifters move fine... And bet distro will turn fine.....

Now got to button everything back up over the next couple days.
Thanks bax.....
