I have a 74' 351-2v cleveland engine and im looking for a non-serpentine belt diagram having trouble getting the belts back on in the proper order

 

Are you sure? If so, you'll want to find the diagram for whatever car it/the accessories you've got on it came from. Clevelands were never offered in these trucks from the factory. In '74, the closest thing to that displacement was the 360 FE. In later years, it was the 351M.

But if it's a non-serpentine setup, everything spins the same direction, so it's just a matter of getting V-belts the right length on the pulleys that line up with each other, right?
