Is swapping a 440 automatic block into a '64 318 full size car a doable thing? Is the 727 trans the same etc., etc.

Trans is different you’ll need a 361-383-426 trans (cable shift) unless using a floor shifter, you’ll need the steel engine mounts for the engine. IF it has a 727, (more than likely) driveshaft will work. Very easy swap

I have the trans and driveshaft, The valve body is for a console shift but I likely have the rooster comb and manual valve if needed. PM me if interested

The only part of the trans that needs to be swapped is the case. We have plenty of big block 64 cases. easy swap.

When you say "full size" are you referring to a B-body?

"Full Size" refers to what we commonly call a C-body...in '64 that would be an 880. These cars use a unique engine mount.

John, Did the 'full size "C barges" come with 318's? Can't recall ever seeing one that's likely be why we're ASSuming it's a B body

The car is a '64 Polara 500 with a 318, console floor shift and bucket seats.

1964 Polara 500 is basically a B body car, sometimes called an early B body. Most B body suspension parts will bolt on, some won't. Engine location is slightly different than later B body cars so you have to pay close attention to stuff like headers.

Find the correct steel engine brackets and you can reuse the isolators.
Like DVR said, change the main case and reuse all the internals of the 727, reuse the trans crossmember and mount.
Later model 67-72 exhaust manifolds fit perfectly, reuse the starter, alternator and even the converter.
Would need B/RB alternator brackets, and the correct oil pan - 62-65 B/RB engines set further forward than 66 and later.
If you use headers make sure you verify what you buy will fit the 62-65 chassis.

I have your trans and driveshaft. Already has the correct valve body for the console shift. might be able to find one of our transport guys going your way. Might even be able to meet them somewhere not too far away. I have no use for it. If interested PM me

According to my limited research, 62 up the smallest was a 361

The 1962 to 1965 BB V8 K members put the front of the motors further forward than the 1966 to 1973 did in relation to the trans mounts and firewall sheet metal, my message is that you can either swap in a later model K member or change the oil pan so the sump won't hit the steering linkage.
I like to swap the K members myself so the cars can get better traction and handling That also makes the header selection better

He said 318 that’s why I said a poly. LA 318s came out in 67 I think. If he has the 361 nothing needs changing

v-8 K-frames from '63-'65 are all the same save for the Hemi K.

Very easy to swap in the engine with the right brackets. A guy named William Cowger used to have the brackets and hardware for this but I've lost his information.

I chose to keep the early K-frame in my car to use all stock components and make getting to the bellhousing bolts easy and maybe bolt on a crossram after I'm tired of going fast.

78030 Hedman headers work really well on this combo if you are so inclined.

I believe the 62 up poly's were 318's Correct me if I'm wrong on that

i believe you are correct; 318 poly motor 62-66 in the states, 67 in canada.
