Just depends on what you're looking to gain, the Andrews 520 doesn't look to be that much different the the SE515. Most people dumping the 515 are looking for more TQ down lower, not sure you numbers are going to change that much.

Here's a link to a similar Stage IV build that your talking about.

I love the Andrews cams, I have it in my shovelhead lowrider for 30 years and it still runs very strong. I now have a new Softail Slim and when it comes time to change a different stage it will be Andrews.

Thanks for the reply, be interesting to see the specs, I'd suggest replacing the plastic lifter guides with S&S lifter cuffs, great low cost upgrade, be careful removing the guides as some have had the bolts break off when trying to remove them.
