Slanted Goals

The date(s) on the bearing are irrelevant. Who knows how long the bearing might have been sitting on the shelf (and who cares). I have bearings on the shelf that have been there for maybe 20 years. What you need to do is measure everything. What bore is required for clean up, and what bearings will be required, after the crank is checked. Determine what deck hight, and head CC's you need, for the compression ratio you want. FYI, if you use an auto trans, that is 1967 or older, and the crank is 1968 or newer, you will need to use a spacer "ring" in the end of the crank, and a 1968 or newer flexplate.

I agree the dates on the bearing shells may not always matter but in this case, it does correspond with the back story I got from the challenger.

Thanks for the info on the auto trans. that is the kind of info this thread is intended for to help out anyone else rebuilding one these engines as well, however for me, I shouldn't be having any flexplate issues :)
