Just in "theory" Alfa Romeo made a straight 8 cylinder
engine using 2 alfa engine in the 1930s, other car
companies also did this in some form or other.

There is a 3 cylinder all alloy HR10 and HR12 and
just wondering what it would be the best way to tie
2 together to make a lightweight engine for a 240z?

Its just for chatting but someone could be interested? :)

Id love a straight 8 using 2 A10s or A12s but weight
of all alloy 3 cylinders and the smoothness of a 6
is hard to beat.
