    I went to change my oil the other day and had a problem finding the correct oil filter. every time I changed it before I just looked at the number on the filter and bought the same brand, no problems.

    well, this time I decided I wanted a fram filter, so I looked the number up in the book and bought a filter, only it was the wrong one. I assumed that the engine came from a different year so I tried to cross-reference the number from the one I had but I couldn't find this filter on any GM application, so I called the filter company and asked them what vehicle it went on, and guess what...its for a f*rd 302! I pulled it off of my Chevy 350, I have no idea why that is the one that fits, but when I bought the fram filter for a f*rd 302 it screwed right on.

    if anyone can tell me how this happened I'd really like to hear it.

    Josh,

    The problem is that you are using a Fram filter on your chevy. use a Dana filter. Frams are OK for air, but never for oil.

    How about a picture of that beauty yellow beast with the softtop?

    As Harry said, Fram oil filters aren't really all that good until you get into their racing filters. Personally, I'd stick with an AC Delco PF-35.

    Have you guys had a bad eperience with fram oil filters? I have been running fram on all 7 of my vehicles, and used fram filters for 20 years now with no problems. The vehicles I have with high mileage run as well as those with low mileage(if 70,000 is considered low by today's standards). Canister filters for my big trucks I usually purchase through NAPA. I'd like to know what problems you have had, maybe there is some info out there that will convince me to switch. BTW a Fram PH13 fits small block chevy.

    Who put that Ford motor in your Chevy? HMMM, If it is a Chevy 350, then it sounds like you might have the wrong oil filter adapter. That is the little metal assy that the filter screws onto. It is held in the block by two screws. You could remove it and take to an auto parts store to compare it with a known Chevy unit. Of course, I'm probably totally off base. JT

    jst12: actually I think that you are exactly right, I just didn't know that a f*rd adaptor would screw onto a chevy oil pump. when I get more time I may try and fix it but right now I've got bigger fish to fry. just thought that this was an odd problem that you guys might find interesting.
