ID these Ford V8 caps

I picked a pair of these up this last weeked and just can't figure out what they are off of. My guess is they are from a big truck. The mounting ring is 10". Here are some pics with other caps to compare the size.

 

Cool is what they are!!!! Dig that giant V8 emblem!!!

 

I agree with your big truck application guess.

 

Those are 38-40 Tonner...



41-47 tonners used a similar hubcap with a Ford script rather than the V-8.
