I want to lower the engine block with new custom motor mounts, and the would collide with the bosses marked red in the picture. The bosses are on both sides of the block.

Would it be safe to grind 1/8 of an inch off of them (green area) to make room for the higher motor mounts?

:unsure: I’m wondering if it was casted in the block to help hold the complete assembled engine in some sort of cradle during shipment to the vehicle assembly plant.

Hard to see the cast on the left. Is it C8DE-6015-C ?

If it is, below might be the correct de-coding.

C8 = 1968
D = Falcon (model the part was developed & billed for)
E = Engine (design engineering office that created the part)
6015 = This is the actual part number for the block
C = This means it was the third block designed for a 1968 Falcon (Note: C might not represent 3rd block design)

After search for over 2-1/2 hours, I found that 170 blocks also have the bosses.

How many freeze plugs does your block have on the passenger side?

I checked out the Ford 200GF-6005-A industrial engine and it has bosses.

It looks like they could be extra bosses to be machined and tapped for different types of mounts.

From what I seen in pictures from the bottom inside of the block, I think your fine grinding some off.

My casting is a 66 200. I see nothing on the inside that would be a problem. The distributor side is close the the drive hole on the inside, the other side there is nothing 👍
The area marked in white is where the boss in question is

That is exactly what I see.
 
Thanks everyone, seems I can grind some material off, good news for me!

@63 Sprint the number on the block is: C8DE-6015-B
The bosses are not machined on the underside, they are located above the oil pan mating surface
