Does anyone know if I can get a sbc serpentine overdrive pulley?

I'd love to have my ac compressor/alternator/water pump/power steering turn faster when at idle which I tend to do a lot of.

Just with efans (no fan clutch) getting the engine from 500rpm at idle in drive to neutral at 800 rpm my ac drops 20* vent temp.

Could probably eliminate the need for my second alternator too!

I emailed March a week or 3 ago and haven't heard back.

 

I am sure you could easily fab one up.
