Technical Swapping a 237 for 265 in 46 desoto

Good morning, hope everyone's having a great day.
Title says it all, I have a very tired 237 in my 46 I and a freshly rebuilt 265 fall in to my lap on the cheap, the really cheap. Hope to put in 265 later this month. I have a service manual just wondering if there are any tricks or tips anyone could share. thanks for reading this!

P.S. sorry if this thread isn't in the correct place

 

should be a bolt in deal but for a few minor items, if that. Both are the longer block Mopar six. I had a 265 in a '51 Dodge some years ago...loved it. It was converted to a fully manual 3 speed with O/D and
great for both in town and highway. But even with Fluid drive (assuming you have that) you should easily notice the difference.

Whew! Relief... Thought he was gonna transplant a Mouse for a minute!

 

LOL I thought that was what he was talking about and I was going to applaud.

 

At first glance, I thought this thread was about the mouse motor but as soon as I found out that it wasn't, I cried

 

...and I cheered........

It never occurred to me he might be talking about a Chevy
