In maybe 2002 Fred Dannenfelzer's lakester engine looked normal but with E/BFL on the body . They had a 180 deg crank and 4 pistons and the second head to cover the blank holes .

  I'm pretty sure Velasco's made a billet crank for that motor with the correct firing order and the Wesch @ Leggitt E class lakester used bob weights and uneven firing order but not positive. Both haul asz and I remember the Wesch @ Leggitt lakester shaking the ground as it went by.

The variable displacement production car engs just disable the valves---use the cyls as air springs  just stop the valves from operating  Gm fiqures 2% loss due to friction.

I think it would be neat to have engines that snapped together like legos. A "master" engine connected to the drive that could allow an identical engine be bolted to its front and connect to the crank making the engine double in displacement.

     Look at the 2 250 OSSA engines put together for the Yankee 500 M/Cs late '60s-early '70s.  IIRC there were at least a couple independently built with 2 additional cylinders for 1000cc and road raced.
