I would like to see a 27L two-stroke van! They already use engines that size (WWII Merlin) for tractor pulls and such, so I say someone should make a two-stroke of that size and put it in a Ford Transit or something, then take it to the drags. You have to ask yourself, what would 12 gigantic expansion chambers sound like with no mufflers?
There's my random idea for the day.
