Scale Model Running Challenger Flathead V8 By Ron Colonna
Bore: 1 in.
Stroke: 1 in.
Displacement: 100 cc
Max RPM: 6,000
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.
Scale Running Model Harley Panhead Engine by Ron Colonna
Bore: 1 5/16 in.
Stroke: 1 1/2 in.
Two Cylinder Four Cycle
No Castings Used
This engine was scratch built to a scale of 2/5ths or 40% of full size. The
bottom end was taken from a drawing of a Knuckelhead engine that I puchased
on e-bay. The top end was patterned after photos taken from e-bay of Harley
parts for sale. I also bought a Harley repair manual that helped with the
oil system. The crankcase was split into three sections instead of the
usual two for ease of machining. The ignition is solid state and I use a GM
coil which fires the two plugs simultaneously. Timing is advanced and
retarded with the timer body. Two rotating magnets fire a Hall effect
device at the proper times as per full sized points. The engine is large
enough to produce that lovely V-twin sound.

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
Flathead Ford Engine Start Up
we found this in a field. we kept the stock crank, rods, and pistons. this
has new valves and guides. new crane cam, and aftermarket edelbrock heads,
with fenton duel 2x2 intake with a pair of rebuilt holley 94's. i added
headers with harley davidson mufflers, and a high torque mini starter. ive
had some of my friends laugh at my color scheme, they thought it should be
in a circus. a girl on a facebook page thought it was a spaceship so we
launched it today.
