65 cuda 273 to 360 tranny hookup

You got some very good info on the tranny / torque converter changes required.

As for the exhaust, you can either bolt on your original 273 manifolds to your 360, and they fit just fine, or go with later 340 HiPo manifolds (VERY pricey) or headers.

Your original motor mounts from the 273 will work just fine on the 360. I just put a photo in another thread showing the driver's side mount, and explaining how the passenger side mount will work. Look at the Motor Mount thread just above this one.
