Oil Filter Recommendation

I have a '70 mildly modified 460 in my F150 that is for street use. I have seen a no. of posts regarding using the 2 quart oil filter. I am interested in using one to replace the Motorcraft FL1A. I have seen recommendations such as the Hastings LF426. I have looked at this filter as well as other 2 quart versions such as the Motorcraft FL299 and Wix 51773. All of these filter have an anti drain back valve, same bypass valve settings and same flow rates. The differences lie in the mircron ratings. The factory FL1A has a 20 micron rating while all of the others I have listed here have a 30 or greater micron rating.

I am not trying to extend the normal oil change interval.

Is this difference in micron rating a concern for my application?

Any recommendations on which of the above or other 2 quart filter that I should be using?

Thank You

I use the FL299 on my '78 F350 race car hauler. It has the factory oil cooler setup and gives plety of room for the long filter. I have had no issues since switching. I bought a case of twelve at a local swap meet for a buck a piece , figuring I couldn't lose.If you have the clearance I'd run it and you can't go wrong with Ford filters, some of the best IMHO.

It is good to hear from someone who has success with using the larger filter.

Napa 1714 (Wix 51714) is what Randy Malik recommended for my engine.

I just looked up the specs on the Wix 51714 you suggested and it looks like a good sized filter to use as well. Thank You.

The problem lies in that a lot of applications can't fit that big filter in the space allotted.

Assuming that space isn't an issue and these larger filters do fit. Is the difference in micron rating or any other spec going tomake the filter not as effective as the one that is factory specified and hurt the engine?

If you can measure 10 microns , you're a better man than me! I don't see any downside to a slightly less restrictive filter ( 20vs30 microns). I do see a plus in the large increase in filter area . Something in the 30 micron size will easily flow through the .0005-.001 thick film of oil flowing through the bearings. If the space permits ( mostly trucks) I would ( and do ) run the FL299.

Sounds reasonable. Thanks for the feedback.
