The only reason the water jackets could be considered bigger in the 226 is due to the cylinders being marginally (less than a quarter inch) smaller. Not enough to make a lot of difference in water capacity inside the block, and could be more than made up for in the radiator.

Another thing to note is the crank and rods in the 254 are substantially beefier and heavy duty than the 226 parts, even though they are the same stroke.

But again, most of the external parts are the same; water pumps, timing covers, motor mounts, starter, generator and brackets, distributor, oil pump, oil filter canister, oil fill tube, wiring and brackets, etc.

Anyone got an extra 40 over 254 piston and rings kicking around? Used condition would be just dandy.
Could use one to get this 254 back together.

You should also ask if anyone has a 0.040 over piston and ring combo from a 337 flathead V8. Both engines used the same pistons.

I used to have a set of used 337 pistons hanging around my Dad's garage. I'll have to look around and see if I still have them and if so what size they are.
