451 overheating, even when moving

Your very welcome. Zero dollars to try the towel thing. Also it doesn't matter if you have a fiberglass or steel hood, if that seal is missing it's going to make your car run hotter. There's a reason that Ma Mopar put them there. Trust me if it wasn't needed they wouldn't have spent the money to put it there. Hope this helps.
I have a fibreglass hood as well with a big 3 or 4 inch scoop, so it couldn't hurt to try this. Thanks!
