I am researching custom bellhousing sources, to make unusual engine swaps more viable. That how the 6.2 GM diesel did it - a custom-made bellhousing.

For the truck group I think the only way for a high-MPG truck to go is diesel. Not only is it more efficient and its high torque allows long-legged gearing, but a fairlt strong diesel pays no penalty (beyond its weight) for low-load operations.
