I agree. Even the MBX truck series measures out to more or less HO scale. The regular series fire trucks are, IMO, in this category. I have purchased older Road Champs, Code 3 and Corgi fire equipment which I think is much more proportionate to MBX or HW "1/64".The fire engines do still look good in 1/64, but to look right with the rest of your collection, shouldn't it also be 1/64 or at least close to that? Just my opinion. They look silly displayed next to the fire and police cars.
