the TC will have some weights welded to the face of TC for a 360
a 318 does not,it may have some weights on the edge of the TC to make it a neutral balance only
a 360 Tc on a 318 will vib real bad at idle and in the upper rpm range,it will wipe the main bearings out in short order.
its hard to miss the big weights on the face of a 360 TC,they will be between 2 of the TC/flex palte bolts
older ones with a drain plug will have 2 weights on each side of the plug on a 360
later 360 TC will have 1 big weight
225/318/340 use the neutral balance TC,so any from a 904 with this engine combo is good to go
if you have a 360 TC you can knock the big weight off and run it behind a 318
