i just did this exact swap....a 440 into a 67 cuda i used the later water pump housing that exits on the passenger side and im using a 26" small block C-body radiator from a 72 fury. my car was originally a 383 but when i got it the k frame and all BB stuff was missing.....so it was basically a regular cuda with BB vin number when i got it .......the engine is a 440 out of a 67 GTX......with the cars original 4 speed. ....the hardest thing about this swap is the z-bar bcoz i used the B-body HP manifolds that came with the engine.....if you use an automatic this swap is going to be super easy......the steering column will need a mega trim back.........if you know how weld then i would suggest putting the engine in with trans and bolt up to the trans cross member .....take measurments and fab your own perches...it makes a better fit..... i had shumacher mounts for a time and i dont like them bcoz you have notch out the k frame to use them and that reduces the strength of the perch and the driver side mount does not have complete contact on the perch........the shumacher sales ppl always try to sell you the torque strap...with good reason bcoz the mounts dont hold their own with out the torque strap.......
as far as low compression 440s ...i also have a 71 dart with a later low compressions 440.......the torque the engine has in the light weight car makes it a blast......the low compression 440 is my Daily driver.....it is reliable. low maintance, and still makes the car very fun...dont throw a blind eye at the later 440s they may not be race engines but very fun still ...usually they have Electronic ignition distributors, they play well with many types of carbs......and look sexy as any BB under the hood..
