Topic: 21 stud year identification


rbone    -- 08-31-2015 @ 12:55 PM
  Can anyone help me identify the year of this 21 stud? The left side cavity next to the motor mount appears to the deeper than the right, which I believe indicates a motor made after '34. It is hard to tell from the picture though, and this is the only picture I have. At the same time, the intake manifold is pre-35 (no tubes showing) and it has a 33-34 oil dipstick and tall fuel pump stand.

Any help would be appreciated.

Thanks,
Ron

  Does the oil pan have a breather on the RH front , at the rear of the crank shaft pulley (Small triangular shaped metal can) if so the engine is 35-37. The early 33-34 engines do not have an internal breather and the oil pan breather is not there. Beside the 33-34 oil pan and the later 35-37 oil pans differ very much.
