Now if someone can figure out a way to arrange a
(Lego) V8 crankshaft to bend 4 directions instead of 2, I will repent from
the sin of butchering Legos!

Here is my V8 with 5 bearings. It has standard small block chev firing order,
and uses the FOS system to simulate spark plugs/injectors. The only downside
is that using the Technic mounts means it doesn’t have the correct 90 degree
angle between cylinder heads.
I’ve also found the friction is somewhat greater than normal, this may be
because the crankshaft pieces force a width slightly greater than 2 studs,
but I haven’t tested that theory yet. I built it for use in another project
which has been on the backburner for a while.

Good design Ross!
I was actually talking about the crankshaft; not the firing order. To clarify
more, I meant that if someone can make a crankshaft that goes 4 directions and
also fits into TLC’s modern cylinder-piston design (while also not changing
their tight “V” design), I will implement their design and quit butchering
legos. Whenever we get a new camera cartridge, I’ll post a picture of my
butchered 4-directioned V8 crankshaft.
However, your design for “firing sparkplugs” is great. Someone who builds cars
a lot (like Paul Boratko, Misha Van Beek or Nathanael Kuipers) could possibly
implement that into their sports car designs!

| (...) It's hard to see in those pics, but the crankshaft DOES go in 4 directions to get the correct firing order, big ends 1&4 are 180 degrees apart, and 2&3 are also 180 degrees from each other and 90 degrees from 1&4 (see below). The extra stud (...) (20 years ago, 20-Feb-05, to lugnet.technic, FTX)
