I am in last phases of my 51 restoration and waiting for some information, so I started doing some investigation work on next project.
I have a Y block with an automatic which was supposed to be a 57 312. I believe the engine is not a 57 but most likely a 56. The numbers and the distributor seem to bare that out.
I am not as confident on the transmission. Based on the pan and number of bolts it appears to be small case 3 speed. The numbers on the case are a little confusing. The only numbers that match that I can find are from a 55 Mercury.
It is definitely air cooled because I have the fined torque converter on the shelf. I was mainly wondering if it was a 56 like the motor or a 57 like it was supposed to be. The casting number are a little strange and do not match any charts I have found.
