v-6 vs. f-head radiator differences

anyone know if the radiators are different sizes and primarily if the grilles are different sizes on the boxed section where the radiator bolts to the backside of the grille for the 225 vs. the f-head? Thanks guys.

 

Re: v-6 vs. f-head

there are 2 for both
17" wide and 22" wide

 

Re: v-6 vs. f-head

IIRC, the V6 grilles center the radiator, where as some F grilles are offset. if this is wrong, someone will correct me. I had an M38A1 and its rad mountings were offset to one side.

 

Re: v-6 vs. f-head

my '66 has a slight offset, just like my m38a1 grille.

factory extra cooloing had a 1/4" taller radiator. Unsure about the 22" ones, as my parts '71 has an aftermarket alum one.

 

f-134 are offset to drivers side and v6 are centered i may be wrong but all i have seen are this way

 

how far offset are they? The mounting holes for my radiator are 24" on center, so sounds like I'd need to fab some bracketry out further anyway, so I may be able to get it back centered unless it's waaay off to the side.
