Would surely appreciate info on engine mounts to place an early 427 center oiler into a 1967 Mustang FE car. I know the later FE motors have 4 bolt holes as opposed 2 on the 427. Is there motor mounts available? I'm sure I'm not the first to try this. Thanks, Joe.

I put a 427 in my '67 Cougar in 1968. The engine was assembled from parts I gathered from one place and another, and was based on a block that was surely either a '63 or '64.
I used the '67 Cougar mounts, and I remember having to 'mess' with them a bit. That's a long time ago, but I believe I simply removed the mounts from the Cougar and either drilled a hole or elongated a hole. It was NOT a big deal. When you get the stuff in hand and match them up the answer will be obvious.

+1 You can make the block plates work.

Very helpful thank U.

Here’s a picture of the ‘67-‘70 Mustang/Cougar FE mount plate and a ‘64 427 with the early 2 motor mount block holes. The mount plate will only have one hole that corresponds to upper early block pattern. The forward wider spaced holes will be unused. As was suggested, there is enough material on the block plate that you can drill the other lower hole that’s needed, although it is close to the edge. My suggestion would maybe be to use a later block with the 4 holes if available to use as a template, or to make a cardboard template, so you can bolt the mount plate to the block and know it’s lined up properly before drilling the needed hole, so the mount plate doesn’t inadvertently wind up “tipped”. If because of manufacturing tolerances you find the needed hole is on the edge of the plate you could weld on a slight bit of steel plate extension in that spot.

2 of the bolt holes in the late blocks is in pretty close to the same spot as the early 2 bolt blocks,but the frame perch in the mustang is not centered under those 2 holes like it is on the Galaxies,it is centered pretty much midway between the 2 sets of holes on the later blocks.When I've seen early blocks used in later cars they usually fabbed a plate that covered the 2 holes in the block with holes to allow bolts to go thru the mount,the plate and into the block and then had more holes for the mount to bolt to the plate,and then they had straps welded to the plate to pickup bolt holes elsewhere on the block.I don't know if this is necessary but the logic seems sound.

The 2 rear most bolt holes in the later blocks are in the exact same place as the 2 bolt holes in the early blocks. That way the later production blocks were able to be used as replacements for the early blocks.
See my picture above, that’s an actual FE Mustang/Cougar block plate on an early block, just need to drill one hole. On other FE powered vehicles there are various other methods needed to adapt.

Wow Kevin, You've removed any guess work for me. lol Thank You very much for the pictures. Made it easy to understand.
