hemi dart 67, I have a 5.7 swap running in my 67 dart, mine is 727 not 545rfe, but I may be able to help ya a bit. shoot me a Private message, or post questions in the Hemi swap section and Ill try and help.
Turbo freak, I didnt have to cut my inner fenders at all, I did have to cut the collar back on my column, its in my build thread (which I never update). As far as fender cutting goes, I know TTI has measurements for the correct location of the crank/engine on their site, may look into that before ya chop, doing the column mod may get you off that fender too...
