That's sort of what I've concluded. Is that what you did, or are you using a remote filter? Also interested in what you used for headers.? I used L&L for my original swap, but I need 2" primaries with my new engine and AFR heads. Only 2" I can find are the #9229 from Mad Dog Headers. I'm waiting on them. Hope they fit, as they're fenderwell exit. Do you have a build thread?
OK. Time for an update. I got a new Ford Racing 90 degree adapter that takes the smaller "500" filter and did a bit of modifying with plasma cutter, so the oil filter issue is dealt with.
Finally got my headers from Mad Dog. These are not a quick bolt-on, but again, some help from the plasma, cutting out the plastic fenderwells, and moving the brake valve block, and I got them in and mocked up on a bare block/heads. These fenderwell exit 2" primaries to fit the AFR heads, so they take up quite a bit more real estate than my old L&L/Doug Thorley headers.
Nice to make some progress again.
