Not sure if this is already well known or not, but I got myself in a bind and needed an oil filter after west marine closed. I typically use the Quicksilver 35-866340Q03 on a 4.3L w/ a remote oil filter. Anyway I had the remote filter in hand and took it to Advanced auto and found that the AC DELCO PF454 was an exact fit. They're also at least 1/2 price, though oil filters are cheap enough not sure it matters. Just putting this out there in case anyone finds themselves needing a late night oil filter.
