Here's my number off the block. I can attach a picture too if anyone wants to see it. 12 C8DE 6015-B Now, I used the handy dandy little search button and I came up with '68 Falcon Engine. I don't know what the rest mean. Any ideas??
Just a run of the mill 170 or 200. If you look towards the rear of the block on the drivers side, there will be a flat area on the block with the last six letters of the V.I.N. stamped in from the car that the engine originally came out of.
