Hi guys,
I'm swapping a 440 in my 360 Duster and changing all the seals and gaskets. And of course, while trying to take out the rear main seal it came out in pieces- the old rope seal. I removed the crankshaft tonight and noticed the 1 and 2 caps were switched and that the notches in the connecting rod bearings didn't line up either. Is this a problem, should I be worried about putting it back together that way? Did it come from the factory that way, or did someone tear it apart before me and put it together wrong?

Thanks,
Dan
 
It's been apart and you will get a thousand different answers. Pictures to start with... then did the engine run?
 
Unless that motor ran like a scalded dog before you got into it, I would tear it down and build it right, hell what am I saying, I'd tear it down anyway. The factory did some weird **** but something like that, I don't know.

I would take it in have it line honed, hot tanked and new cam bearings installed. Of course you'll need to replace all the core plugs too. A few $100 bucks & piece of mind.
Also make sure you gas off the crank thoroughly including brushing the oil passages.
