Here's a few tips,mostly from memory,so here goes,the difference in the
motor mounts is on the driver's side,if it's like the 318 to 360 swap I did
in a 72 Charger years ago,on one of the bolts, there is a space left between
the mount and "ear" on the block,even after the bolt is tightened,at the
time,I didn't worry about it and drove the car for a long time without any
problems,if it bothers you,fabricate a spacer. The 727 trans is a
bolt-in,but it is longer than the 904,so you'll need a different drive
shaft, Try a driveshaft out of a 75 or newer 727 equipped Cordoba, Charger,
Magnum, it should be real close. Your exhaust manifolds will work,along with
the radiator,etc. but make sure you have the proper oil pan and pick-up
tube,the 318 pan/tube wont' fit a 360, ( Main journal size is WAY
different ) if the 360 came out of a truck or van,you'll have to replace
these parts with the proper 360 "car" pieces...
