where to find 2 groove pulleys?

[bigboar]

hi all,
I am wanting to add power steering to my 305 v6 and am curious if anyone can tell me where to buy a 2 groove water pump and crank pulley?
I am going to use the power steering pump from an 85 c10 donor so I know I will have to fab up a bracket for that. Any help appreciated!

I would think a donor engine is your best bet. I got a set off a 351 I picked up. I'm not sure, but I bet the bigger trucks would be a better chance, something that would need the help turning!

I ended up modifying my stock pulleys by using a small block chevy crank pulley and cutting it apart and adding rows to my stock pulleys. I had some help from a friend that owns a machine shop. You can check it out in my build thread if interested.

Here is a set. Pretty hard to find.

Interesting. My 351 has a 6 groove crank pulley...
