87 302 engine, passenger side water hose, 4 bolt crank. Driven for 100s of miles with 1v pulley.

Im installing an AC and looking for a 2v pulley setup. I measured the crank / water pump offset and I get 2.5”, but understand that’s not common. Any thoughts?

Here’s a photo of the dampener offset from the oil pan - roughly 3/4”.

I must have measured hundreds of pulleys to find the "magic conversion". Never did. Your best bet for success is to spring for the "5.0 conversion" damper. That will allow direct bolt-on of 65-69 pullies, brackets, and accessories.

Save yourself a lot of headaches and pick a year.

Then source a matched set of everything.

You will drive yourself nuts trying to shim mismatched pulleys to align.

that’s good for me. I’d like a 66 setup with an 87 engine. Any suggestions? If I understand correctly I need the 50oz conversion damper for starters, correct?
