This 1:4 scaled Challenger V8 displaces an entire 100cc. It might be small, however, all of the needed parts that make an engine are there.The amount of determination and patience that went into this scaled-down flathead V8 must be insane.

The engine burns gasoline or methanol (methyl alcohol) on dual electronic spark ignition and incorporates a two-stage pressurized dry-sump lubrication system.You can see and hear video of it running.


This flathead challenger V8 resembles a Ford, however, its exhaust and intake ports are situated on top like an old-school Cadillac or Cord L-head V8.
