Hi all, the simple explanation for the XP-361 is it's the easy way to differentiate the XP-360 180 hp parallel valve engine from the 200 hp angle valve engine as one of you so deftly noted! Web site will be updated shortly as well! Both engines are actually 361 CI.
Just curious to know if they also plan to offer Engine Build School for the -320 as they do for the -360.
I'd love to build my own engine, even if currently all of this is a dream.

<Oops>Sorry for the stupid question, I just found the answer (a YES) reading another thread called XP-360

It is a wise person indeed who will take care consider more than price in these things. There is a lot of time at 12,000' above the Bitterroot Wilderness to think about the quality of one's powerplant vs. the price paid, as I did recently
I think Superior makes a better kit for a handful of reasons that may or may not be of interest to you. They've made some key improvements to the Lycoming design that you won't get from ECI. The beefed up block is worth the additional cost alone (to me at least), after seeing my friend's Mooney with a cracked block on his angle valve IO-360.
Superior appears to have done their homework on the research and engineering. By engineering out the few failure points that were known on the Lycoming design, they're added value that's worth money to me. ECI was slow to own up to manufacturing defects in the cylinders of a friend's P-210 that later became an AD, and so I question their integrity as well. Your mileage may vary, of course. When the time comes, I anticipate that a Superior will be going in my -7A.
