I found a single groove pulley and wondering if this will interchange?
 
I believe so, except for some years had the "odd hole" and you can only get 5 bolts to fit. I once had an aftermarket AC on a 440, cast iron add-on pulley for the AC stacked in front of everything else. Bolted right on to the 340 when I swapped that in!!!

Now as to whether what you have will "line up" with whatever else you want to use..........don't know
 
You won't know until you try it, but I don't believe it will.
 
I ordered the pulley. I'll report back. I'm pretty sure it's going to work.

The only thing being driven is the alternator and I really wasn't crazy about underdriving that because I have fuel, fans, pumps, being driven by the alternator.
 
So, is the alternator in the stock location? What cylinder head? What dampener? I run a March single groove for 68 small block with stock heads and stock size dampener. The eddy head moves the alternator forward and there is one dampener that sits farther out. Fluid dampner? Pulleys are like the shell game and trying to find the pea! If that one doesn’t work. March might be able to help.

I already have a functioning setup. You're right it's a juggling act getting pulleys lined up but I'm pretty sure it'll work.
 
The bolt pattern will work, the offset and diameter is a different story. It's measuring time!
