Not all of it. Less room under the hood as the firewalls are in a different location. Wheels/drums are 5 on 5”instead of 5 on 4-1/2” Some guys complain about upgrading brakes.
A friend has a 56 Montclair with a Windsor engine and has cooling problems due to the length of the newer engine. I noticed it looked like very tight fit. Many Ford guys move the radiator forward where the 6 cylinder had it. Not sure on a Mercury but I see no reason not to do the same. His has not been moved.
That might be a case where you would want to use the early "short" water pump and harmonic balancer mentioned in the 'Sticky" file. If you use a later Windsor with Serpentine they may be a little shorter than the 70's belt drives.

Hardly chebbie chit - Merc used 5x5 - just another oddball FoMoCo move. Same thing with OT 72-76 Birds and Mark 3-4s.
I wasn't talking about the 5x5 pattern. Lic, Merc and 2 Edsel models used it. I was talking about the 4 3/4x5 it is the Chev pattern. BTW, if your confused jimmy six, has since edited his post to 5x4 1/2
So I picked up a 302 and a t5 is the clutch the same as a Ford? Does the fox body motor mount trick work?
Read the notes under the pictures, so you position the motor back towards the firewall to gain water pump to radiator clearance. https://www.jalopyjournal.com/forum/media/albums/289-302-351w-swap-mounts.41498/
