You can get a great engine from Wentworth. I highly recommend doing your due diligence.
Many years ago at OSH, I inquired about an IO-540. They tried to sell me one out of a helicopter and told me it would be just fine in my RV-10. Thanks to both Alan Barrett (BPE) and Lycoming Tech Support (it's nice when all of them are within walking distance) advised that that particular engine wouldn't be a good choice and it would be expensive to alter. Don't ask for specifics, because I can't remember the details anymore. I'm just thankful that I got some great advice before proceeding with the purchase.
Personally if I was going to build again, I'd give Alan or Rhonda a call at BPE. They have plenty of options, both with new engines and rebuilds.
