Just a quick post about some markings that I found stamped into the engine block, just below the flywheel.

As you may remember this engine has the Big Bore kit in it, well the previous owner punched the specs into the engine block, where they can only be seen once the transmission was pulled!

In the bottom right corner you can see the ledge where the numbers are punched in.

“840 C.C.”

S.B. WEST – the previous owner

“10.5-1” the compression ratio

“3-78” the date the work was done

should i stamp my inititals here and the date before I button the engine back up?
