For about 30 years I have been dragging around a few parts for a 1937 Indian Chief. I've restored several later model Chiefs over the years but this is my first stab at a pre-war model. A couple of weeks ago I was able to locate a bottom end for the engine with title. Very important since the state that live in will not issue restoration, homemade or a bill of sale. This left me with no "top end" I could use later model cyl's. they would work but would not be correct. They only made the cyl's. I need for two years. 36 & 37. None were to be found at the swap meet were I bought the engine and several phones calls after only confirmed that they were very rare & if I found any they would be very expensive. 37 Chief bottom end.
