Nice one! Obviously one groove instead of two is better, thanks for that info. I've noticed an electric pump for $600 on eBay (which compares to around 400-500 depending on manufacturer for a SD7B10), so I'm deciding between the two options. Where are you planning to mount your compressor?
I looked at the electric option too, and the more I looked at it, the more it seemed to be cost-prohibitive, with a shorter expected service life and more expensive maintenance, as well as a big compromise in the AC system's performance.
The conclusion I came to is that if electric AC were a good alternative, you'd see them on a huge variety of applications.
As for my AC pump, I mounted it adjacent the crank pulley on the right hand side on a 5.9 magnum. I have it pivoting from the bottom with the adjuster above.
It is still in mock-up and needs to be reinforced, but I managed to get it located with sufficient clearance from the water pump inlet and the K-frame in a VC.
I will get some photos of the mock-up for you tomorrow evening for reference so you can eyeball it's relative size to the block etc. :thumbsup:
