595K6 or 590K6, depends on your pulleys. I haven't run one yet so I don't know how much ET you'll gain. I'm not sure where the diagram is, maybe on the Corral?

Here's a diagram I made...

I gain about a tenth and 1.5mph with a shortbelt.

What size do you use for your ASP's Paul?

590K6 works for my ASP's

Chad, did you gain anything with it? I think I may try that next time.

Haven't tried it yet, I put it on last weekend to make sure it fit, but I probably won't use it this weekend at NMRA. Also, I only have the ASP crank and water pump pulley, I left the stock alternator pulley on. That might make a difference in size. Most people told me a 595K6 would work, but that was a tad bit too big.

Most likely it will be either 595 or 590K6, I've heard of some people needing a 585K6.
