Check my reply in post #11.
Besides what I mentioned there, the biggest deal with swapping in the C6 would be the driveshaft. If the C6 isn't the same length as the AOD it would require a different driveshaft. And a lot depends on the wheel base of your E150 donor compared to that of your E250. If you are lucky it may swap over. If not you might have to install a hybrid rear U-joint ( two different sizes ) . Or you might need to have a driveshaft shortened or a new shaft made up. Or hunt down the correct shaft from an E250 that had the C6.

I'm assuming the whole reason you are swapping a 351 into this truck in the first place is because it is a total dog with the 302 in it.. right? Well that is partly because the 302 is a weak truck motor in general but it's also because Ford is well known for installing totally inappropriate gearing in trucks. This being an E250 there is a good chance it has a decent truck axle ratio like 3.55 but wouldn't you like to know?

Just remember the E250 is going to have a larger rear diff. That may change the length of the shaft that is needed. Or at the very least could require a different U-joint. If that is the case then you'll have to install a Hybrid U-joint like I mentioned earlier.

My concern is not whether it will function or not.. it will, my concern is if the gearing is suitable for a truck of this size and weight.

I drove this van through the mountains in northern Ontario and got better fuel mileage than driving in the wind in Saskatchewan. the 302 has to work so hard and it really won't stay in OD unless its not windy at all.

BTW.. you could have used any year 5.0 for a swap even a later EFI motor, all you had to do was strip off the EFI intake and accessories and install the parts from your original motor. That would have also given you a nice bump in power and economy.
