im also in the same boat i got a slant 6 in my 74 dart and im wondering what else would i have to change in order to drop in a 318?i either have a 727 or 904 tranny and from what ive heard either of those will stand up to the 318 but what about the rear end? and what engine accessories would i be able to reuse? sry not trying to hijack your thread but im also wondering about the same thing i bought a 73 v8 k frame that was damaged a bit in the front but decided it would be to much work to fix it then put it in so i sold it and gave up on the idea of doing a easy v8 swap til i heard about these mounts you can use on the /6 k frame
