CVF Racing serpentine conversion kit

Sorry to resurrect an old thread but @dano or anyone else, can you confirm the CVF pulley would be a direct replacement for a small block? I am tired of all the flimsy, flexible chinese parts store pullies. I've had two warp and I'm afraid if I don't get a true and straight pulley it'll take out my pump. My bracket is Bouchilon Performance's factory style replacement. It's a thick bracket so it's good. Maybe I'm tightening my pump belt too much and that's what's causing the warping.

@AirForceRacer hasn't been back in a while. I think I see him on Instagram
