Just another thing, there was no indication that the bearings were going. I'm running solid motor mounts, not solid rubber but solid metal, and can hear every noise the engine makes even at speed. If a bearing had given any indication it was going I would of heard it. And like most other people who drive these cars most of the time I don't turn the radio on as I'd rather listen to the engine
Rod bearings don't fail without a whole bunch of indication....especially with solid mounts.
It might be better to word that:
"Just another thing, there was no indication, to me, that the bearings were going.

A couple thoughts
Since you do have a SUPER rare LH euro I would NOT (as in HELL NO) to a SBC conversion...& I DO like the idea of a conversion...just not in a true LH euro, since they are SO rare.....if you had an older USA 928 then I would convert it...
I would rebuild with a 5.0L bottom end....it will give a bit more kick that you have been looking for and can easily make 290whp....quite respectable.....for not much more overall cost vs a 4.7L rebuild
I am concerned why your rod bearings failed....are you 100% sure that was the failure.....stock 928 rod bearings in street driven 928's last just about forever....I have opened engines that had 175K plus miles on stock rod bearings that looked GREAT.....the bummer is the "replacement" rod bearings are vastly inferior to the older Porsche bearings..several well built engines have failed recently due to the inferior rod bearings (plus tons of 944's)

Buzz, what you did to your car is very impressive, but it IS NOT a restoration...it is a modification. A RESTORATION (by very definition of the word) would mean that you RESTORED the car to its original condition.
Imagine how much it would cost to do a renegade change over if you actually had to PAY SOMEONE to do the work? That work plus the cost of the engine would EASILY cost more than a short block 5.0 EURO Hybrid set up...probably by several times. Don't get me wrong, I love the thought, but it is a daunting project when you get right down to it.

Indications
What would the typical "indications" be?
I've got some strange stuff going on with my car, so thought I'd put this out there.....
TIA.

Buzzdwyer,
I may have an angry mob here later tonight but I won't be home anyway, so here it goes: I'm not a purist. I love the car as it is unique but being smoked by "other" Porsche's (numbers and names withheld on purposes) and every other stock American made late model pseudo-muscle car is not what I had in mind when I signed on. Is it wrong to want a couple more HP without having to spend my kids college funds? I've already resigned myself that the resale value is plummeting so fast that whatever I do to the car is for me. That being said I have no issue with the conversion, that's why I suggest it. More importantly, are you happy with yours?

I like the thought of a 5.0 EURO hybrid motor... You state that you just read this is a known problem w/ 928's, I have to say, I have never heard of a Euro 4.7L spinning a rod bearing before... not that it has not happened, I just have never heard of it happening! '90 and '91 GT's that have been tracked, yea, I am buying that...hear that story all the time, but not in any of the other 928 motors...

If it's money you want to save go with the 5.0 hybrid that everyone is talking about. I am doing the renegade conversion and had/having a blast doing it but it's not cheaper.
