Converter arrived yesterday....next day delivery from Summit! Anyway, rebuilding the front end today and will post pics of the old converter/pump/bushing soon.
I did notice something peculiar on the headers though. The headers are newish and polished, but #6 and 7 both look dull, like they got REAL hot. I'm going to pull all the plugs and have a look. I have a thread going on about a misfire I can't fix, but I'll ask here as well: what could make just two cylinders run so much hotter than the rest?
