Scale Model Running Challenger Flathead V8 By Ron Colonna

Challenger V8 Ignition: Spark 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.

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.

Supercharged home made Straight Eight by Desperate Dan Vid 2
Built in a shed, it fired up first go. I was hoping it would sound real lumpy like a drag engine, but it runs too smooth, and it's too quiet even with unsilenced 9" pipes! The timing was a pain to sort out the Rover distributor runs backwards, I had to take the heads off to work out the firing order!!! See the shed it was built in on Vid 1. Added May 2012: OK, my nails are dirty, maybe because I'm an engineer & build stuff? Maybe your nails are clean because you can't build eff-all & just sit behind your computer? C'mon folk, get a life.





The Smallest RC Engine In The WORLD!
I met Ronald Valentine recently and he says he makes the smallest combustion engines in the world. I am not the expert here, but I must say he holds the title so far as I can see. His smallest engine is less than the size of an American quarter coin and I am really impressed. You can visit Ronald's website and make your own decision, but from my view he has made some really fine engines.
