Do you know of any 350's with those new engines with over 178K miles on them? That would mean you'd have to find a 350 with around 240 - 300K miles on them (how many are there, anyway?) I've seen original engined 350's go 220K miles before any rod-bending. It can happen at any time, apparently, and it evantually does. How many 350's out there in excess of 400K miles on the original engine? None I can document, yet.

I am not saying my engine has failed yet, but chances are, it will. I do not know of anybody in my area who even OWNS a 350 because they are so rare. How do you know they are lasting 3 - 400K miles, no prob(and beyond?)? The engines are just too new, and the cars are too rare. If you could tell me about somebody who actually has a 2nd 350 engine with that kind of miles, I would be extremely interested in looking at it, out of curiousity.

I've seen several 300's (OM603)with over 400K miles, and some had close to 500K miles. Still running, with the third generation heads, of course! My 300SDL doesn't burn a drop of oil!

Sorry if I sound rude; I'm upset, and am looking for a logical solution to a very challenging enigma.
