HSSS
I just read this whole thread and have to admit that you certainly have had more than your share of bad luck with this engine. I also note that you do not seem to be discouraged (except talking about a Vette at one point).
While I read the entire thread, I don't remember seeing it mentioned why the engine seized nor why the belts came off a couple of times. These two things signaled the beginning of the problems and the belt issue has to be addressed for sure.
I know that we all have 20/20 hindsight but as I was reading the first page or two of this thread, I kept thinking "why doesn't he pull the engine and send it back to the builder?". Of course, it is a bit late to consider that option now. FE's are not the easiest engines to work on and this one seems to have a special personality. KC has an excellent reputation and probably could have saved you a lot of time by getting everything back on track immediately. This is simply an observation, not a criticism.
I wish you the best of luck. You sure seem to be taking all of this in stride. I would be freeking out if I had half thess problems.
Regards,
