If seen that in some of the forms people talking about it. I know someone that has a ton of the ignition module I'm going to get up with him and put a different one and try that for a while and see what that does. If that does work I might go junk yard and see if I can find a 300 with that cooling fan. And if I can't find a cooling fan and the ignition module doesn't work i guess i'll take her to the shop cause I'm just about out of ideal to try

Pinging can be caused by improper ignition timing, or a lean condition. What's the fuel pressure? It should be 50~55 with the key on and engine off and 40 to 45 psi with the engine running.

I know the timing should be at 10 degree before. But what is throwing me off is that on the timing plate it has teeth and one spot it has a v. DO I put the timing mark on that or go down 5 marks if its going by 2?

The deeper v should be the 10° mark, so line it up there.

Hopefully the timing setting was your problem.
Here is a list of common pinging causes.
-Fuel octane rating too low.
-Compression too high. (usually caused by carbon build up inside the combustion chambers)
-Over heating of the engine or just an individual cylinder. (Hot spots)
-Knock detector faulty.
-Ignition timing over advanced due to incorrect setting or erratic ignition due to a worn distributor. Most modern engines no longer have distributors.
-Blocked exhaust, giving a high backpressure. (A significant loss of performance will be noticed)
-Note: The tendency to pinging is highest when the engine runs on the ideal air fuel mixture. (14:1) Therefore a mixture problem -running too lean or too rich- will not cause engine to ping.

Ok good news . When I re timed my truck to it quit the spark knocking. But I'm still having the hesitation When I try to start it after i drive it bout 45 min or so. And also when I let my truck sit and run hit try to run hot and I mean hot like the needle will be on the L on normal. And when it hesitate to start today my farther in law said it black smoked a little bit
