The 440 in the 66 will drop right in on the subframe on the 68...no issues at all. And in my opinion it is not easier to swap subframes....that is a ton of extra work for no gain. I pulled a 440/727 from my parts car 71 300 4dr and dropped it right in the hole on my 68 T/C wagon (previously robbed of it's original 440/727), no mods or changes required....even used the 71 radiator and shroud....again direct bolt up with no mods.
