Here is something I have been playing with, Chevy dually, plenty long wheelbase, Gp20, 182 grams, .500 wide rears.

@MacMan, nice dually.  Is that a sheet of lead behind the guide flag?

Cool truck.
Looks like it could have started out as a silp joint chassis,they work nice with cars that don't use wheelie bars.

Is inline required in drag racing or just simpler to build?

You could build however you like as far as motor configuration.

Just back to this thread briefly. I had thought that John Havlicek did one of these motors, but couldn't find the reference, so now I know about when he did it. 

 

The original inspiration for this type of motor was an article in a 1967 Model Car & Track, "The Amp Eater". Here are first and last pages.

I had been thinking about this because I just found a car on ebay that had what I thought was a 26D version of the motor.

But once I took a closer look, it wasn't quite the same thing. A single endbell and a single extended arm, instead of two joined arms.

Joe Mig, any news on your Long John car?
