1974 Dart swinger 318 to 360 swap

driver side motor mount is different on 360 but 318 mount can be shimmed or modified for use...

Most important issue is the externally balanced 360....you need the harmonic balancer off the 360...now you can use the 318 trans if you want..but need a B&M weighted flex plate...

or you can use the 727 from the motorhome assuming it has the correct tail shaft on it..it will have a weight converter for the externally balanced 360

look at the tail shaft of the 727 from motorhome....see if it has a normal tail shaft or has a big brake on the engine of it....I am will to be it is a normal 727
