LT1, maybe not, but the 1st gen (okay, post 86, so 1 piece rear seal, and a block set up for roller tappets) went serpentine before they went to the LT series (2nd gen). Would that work?
FWIW my understanding was the V belt setup required excessive tension to keep the belts from slipping (hard on the blower drive and the crank snout).
Check with JG Loomis, he put an Eaton blower on his, I'm sure he's got pointers on how to do it (even if you use a centrifucal, he already sussed out the drive pulley).
The link to his pictures is in his sig (he posted earlier in this therad).
His thread on his setup is here:
