I need to use an oil filter relocation setup
I have a stef's/B&B oil pan and 1 7/8 Ed quay headers, and the small WIX 51069 filter

I have a 421 SBC, so do I need more flow ? and use 10AN ports?
or is the 1/2" enough?

 

I would need to go check mine but 1/2" lines should be more than enough. My remote filter is mounted on the front motor plate. There is room in the OEM location but I run a System 1 filter so the relocation position makes it a lot easier to remove so I can open it up for inspection.

 

I just checked some things

The 51069 wix filter is 4.33" tall
Wix also has a slighter shorter filter (51046) at 3.8" tall

Would I lose much filtration with a slighter shorter filter?

 

only thing im going to warn you against is using typical braided hose for relocations.

In the last 15~ years I've seen a few engine failures due to the braided hose getting kinked or closed shut somehow.

Instead of that typical hose, use the high quality teflon lined hose, or similar. They make some -10 and -12 so stiff that you can set an engine on it and it will still flow oil.

 

Good info, I'll look into it
