I installed the larger tensioner pulley wheel that came with my kit, as well as the FFR supplied serpentine belt. For the life of me, I cannot get the belt over the idler tensioner..... I rotate the tensioner until it bottoms out and the belt is still too short..... I reinstalled the smaller Corvette tensioner pulley wheel and I can get the serpentine belt over it with plenty of tension on the belt....

Is this common, or am I somehow missing something?

The belt is a 6PK1575, the FFR pulley is approximately 3.5” diameter and the corvette pulley is approximately 2.75” diameter.

I appreciate others experiences.
