Given the number of people here who have done the direct opposite of what you want to do, and swapped a V-8 in place of a six, there should be plenty of them available. It uses the same bellhousing pattern as a 302.

There is quite a bit to this swap.
You would need a different C-6 because the bell housings are different. I think the engine mounts are different. The exhaust is completely different.
As far as MPG you are not going to gain enough to pay for all the parts and labor to do the swap.
If you already had all the parts for free and they were in good shape it would be cost effective. In other words for the cost of buying an engine and trans, exhaust and miscellaneous pieces you could not recoup the difference in MPG savings for many years.

He's right. Unless you have a donor truck and free parts, you won't recover your expense.
