This engine was built early in my gasoline engine building career. I
received the castings and drawings as a Christmas gift from my wife. I had
it running about five months later. This is the engine that creates the
most interest at the shows. So much so that I've had to rebuild it twice
because of wear. As designed, it had some major shortcomings. The conrods
were bronze castings which promptly wore grooves in the crank. These were
replaced with rods machined from 2024 aluminum. Pistons were remade and the
engine fitted with rings made from the George Trimble method. Oil control
rings are a necessity as the engine smokes badly without them. An electric
start system was added and the engine now runs with the push of a button.

I knew a little about the famous Offenhausers, hearing about their
conquests at the Indianapolis Speedway while growing up. I didn't get
interested in building a copy of one until approached by Bob Washburn after
doing my Cirrus article for SIC magazine. At the time Bob was looking for
someone to develop the model, do the basic drawings, write machining
instructions, and build two copies of the finished engine, in a one year
time frame. He sent me all the data he had aquired at the time. I looked it
all over, but had to send it all back. I was busy on other projects and it
seemed a daunting task that I was sure I couldn't accomplish. I didn't
forget the engine though, and some years later, a gift of Gordon White's
book on the Offenhausers from my eldest son, put me in the frame of mind to
give Bob's proposal a try, but on easier terms. It took me two years to do
it all and I only built a single copy of the engine. I put my drawings and
machining instructions in book form and published it myself. It has been a
successful venture, but I was right about it being a daunting task. I'll
most likely never try doing anything like that again. The engine has been,
and is being built in many parts of the world. My copy has been running for
eight years now and is a fine performer with the throaty roar of it's full
