I think it's time for new spark plugs in my 77 Bronco with a stock 302 engine. Any suggestions on some really good spark plugs to put in it?

I have read both of your posts and went through the same problem. Mine ended up being plug wires. If I were you(not knowing anything else), I would try a whole tune up. Thecheapest plugs will work (just in case you are fouling plugs for some reason you arent wasting money) I would take one of your plugs to the store to get them to match it up. Mine were different than what was listed in autozone computer. Had to make two trips. Just some thoughts.

How about the Motorcraft ones listed on the emissions decal on your valve cover?

Yes they are the big ones (so I guess that means my heads arent the origional to my 76 :-[). Being a "smarty pants" is what this site is all about. 1. to help our brothers out and 2. correct the ones that provide incorrect information
.
Autolite 25s. I know they are very cheap and basic copper, but I have tried lots of other expensive ones and our Ford 302 loves the Autolite 25s best. Trust me lol!!!

The sticker on the valve cover has been painted and parts of the sticker has fallen off.
go with non platinums theres no reason to go with high dollar plugs on a carbed engine as they will still need to be replaced in a year anyways.
As for the 3924 plugs well i beleive they are slightly different as they use a washer for sealing were the 25's that are called for use a tapered seat. Also I believe the 3924's have a longer reach than the 25's .750 vs .460 at least thats what the chart says. so basically I'd go with the 25's or motorcraft equivelent.
