I still think Summit could help you. You might have to go to their tech line if a salesman is not helpful enough.

My neighbor has an old 4-71 supercharger. The lack of a good intake manifold prevents using it. But if my turbo idea on the straight six doesn't provide the torque I'm looking for, I may start looking at his 4-71.

Anyway, good luck. I want to see pics of the supercharged truck. And I"m interested in how well it clears the stock hood.
