looking at 2 454 blocks for sale from different area of US, both are 14015445 casting number. These are both MK IV blocks and both have a "1 piece rear main seal" ???

And yes I read the Mortec BBC block listing but it does not say anything about the Rear Main Seal,,, any ideas ?

I have had two 445 castings and both are 2 piece rear main seals. Sold one and will be building the other. What are the numbers stamped in the pad above the timing cover?
IIRC the Gen V was the first model with a 1 piece rear main. Have a friend that put one in his 67 Camaro.
