I have a 1965 Ply. Fury II. I'm thinking about putting a 1972 360 SB in and have a couple questions. Does anyone know if the Poly 318 engine mounts and trans. bellhousing will work with the 360? Also what exhaust manifold will I need to use? I would prefer headers but can't find any listed. Any tips or help will be appreciated!
Thanks, Kevin

The poly is still a small block. The 360 should drop right in, except the exhaust.
Might wanna go to the C-bodydrydock forum to get more info on your 65 as it was a one year only deal on a lot of things.

Mostly bolt in/up.
The bell is the same, don't forget the 360 is externally balanced.
The left motor mount engine bracket will need a little bit of ingenuity,nothing too tuff.
Can't make a header recommendation, shouldn't be too much of a problem though.
Radiator outlets will be wrong, unless you change the 360 front to the earlier 318 water pump.
Did this once on a 64, not much problem.
