Above the starter are the letters CON3 B39. The pad by the distributor is stamped F240J. There are no other numbers I can find on the block (until I clean it more). The head is casting #3836848. The port for vacuum wipers is still in the intake. | | |

I bought this at an auction after a local "mechanic" told me it was a 292. It was to replace the flathead in my '39 Pontiac, now I'll have to rethink the swap. | | |
