Howdy Gang -

While cleaning my storage area out I cam across a FE block, first thing I noticed on the back of the block was "66-427" boy did I get excited, once I was able to get the block out of its pile I noticed that it does not have cross bolted mains, has no check mark or HI on the block, I popped out the freeze plugs and on one side inside the freeze plug hole it says 352.

The block has no casting numbers at all the flezplate with it is a 428 mustang plate - c6ae-6380 b -

The block is drilled for center oiler but also has the side oiler humps that are not drilled.

cylinder heads are c7ae

I going to mesure the bore and stroke in the morning.

my question is Did ford make 390 blocks molded almost like the 427? with the 66-427 on the back?

I have seen several 390 blocks with the 66-427 numbers cast into the rear and the undrilled sideoiler bosses. Story is that Ford cast a lot of blocks using the rear section of the 427 casting die since it was either convenient or a necessity at the time.

Is this Tom, Pop-pop with the white Fairlane? If so I have not seen you at Ocean City the past two years? How have you been?

most fe blocks from that era had markings like that... check the bore... 390= 4.06; 428= 4.13; 427= 4.23.. sounds like you either have some sort of service block or more likely a marine/industrial block.... HTH
