serpentine conversion recommendation

I have not found that to be an issue at all. Though I have not used it with a OEM intake manifold, just a Edelbrock RPM- AG
No pics of my own, but pulled these from another thread:

Magnum with LA air gap intake and serpentine
Not true. While I happen to have a Magnum non A/C bracket, I did initially have the regular Magnum bracket that had the A/C
Sure it technically could still be used, but the belt wrap on the WP is pretty marginal without the ac or Dorman pulley.
