4280 (search for Markiv4280 posts here) has a serpentine belt system on his motor.
I believe there are also pictures of the system on ProvaMo.
Originally , Wade’s plan was to put a Whipple supercharger on the car, but unfortunately, that didn’t come to fruition….
If you search on his username, you will pull up a thread on pulley ratios where he (Wade) talks about his setup.
There’s at least one picture of his engine .
