It looks like a pile of junk! Broken bits, corrosion, missing essentials, and wrongly described on ebay; this is an easy engine to look past if you don’t know exactly what you’re looking for. This isn’t a 1934-1935 Austin engine, it’s actually a 1940 American Bantam three main bearing engine; the famous Hillmaster. However, it is a Hillmaster that had a very hard life.
While it appears that nearly every component modified or compromised in some way, but that doesn’t detract from the fact that it is a three main bearing engine of which approximately only 1000 were made. If enough people are interested, I can post some comments on the condition of the lot itself so you can have a better idea of what you’re bidding on. However, that isn’t the reason I’m posting this engine. I’m posting it primarily for two reasons.
Firstly, the number 65589 does not appear in the production log. Every other number from 65580-65590 are listed, but this number appears to be entirely absent. Perhaps it was a replacement engine, an industrial engine, mismarked on the log, or even for an export car. There are numerous possibilities.
The second reason this engine is interesting is not only because it has the fuel pump mount opened up, drilled, and tapped but because there is a fuel pump included in the lot. As you probably know, Bantams used a gravity fed fuel system which obviated the need for a fuel pump. However, beginning in 1938 all Bantam crank cases had a provision which was designed to allow a fuel pump to be run and all cam shafts supposedly have a lobe to actuate the pump arm. There have been mentions of fuel pumps in club news letters but never which part was actually used. In recent years, there has been little to no discussion on this matter so the knowledge as to what pump could have been installed has essentially vanished.
Does this information really matter? Probably not. However, if you’re like me and have a couple of engines sitting with gaping holes where fuel pumps can be mounted, you may be interested. If you are building a car which is day one authentic, this probably isn’t too helpful but should still be pretty interesting.
I have a hunch as to what the fuel pump may be and will update you if the hunch is correct.
