You are only going to get pinging with a load on the engine. Such as climbing a hill or hard acceleration. If you are hearing the noise when crusing then its not pinging. Retard the engine a couple of degrees if you are not sure. If it is pinging it will either go away or decrease with the engine retarded.

It happens at cruise at like 55-60, not hard acceleration but with any acceleration at all once im already going 55. I would like to run premium but I cannot afford it. I can hardly afford to drive this truck as it is but what do I say older fords are fun trucks to drive. Could I be harming my engine?

Pinging can indeed happen at cruise - it depends on many factors. Whatever it takes to make the engine work under a load.
Overly-advanced timing (be it too high base, or too steep advance curve) can lead to pinging, but overly-high combustion chamber temperatures are another reason an engine can ping (and in fact, both can lead back to one-another). Too lean of a fuel mixture can cause this. If this engine had EGR, but a previous owner ripped it out to "clean up" all the "smog junk," then this will make things worse. A stock engine, properly tuned up with all the original equipment in place will not ping. It's when parts fail, or people who don't know what they're doing try to "fix" what isn't broken that issues like this occur. Pinging often goes hand-in-hand with dieseling too, for the same reasons.
As previously mentioned, pinging is BAD.
