The two "V" 8 engines (that I find hard to call a "V" as they were 180 degree "V"s. as 180 is a "flat" line....as in Porsche's 180 degree "V6" (that I'll never call anything but a "flat 6".)
Porsche never made flat V4's V6'es or V8's.. they only made Boxer 4 6 and 8's
a Boxer 6 is naaaawt a V6 !!!
Completely different crankshaft design !!
Boxer 6


Simpler V6


They have on the other hand made Flat V12 engines for the 917.. those are naaaawt boxers !!!
Reason being, a V crank is much simpler in design and due to engine length and endurance requirements.. a V crank was simpler and better..


Basically the V engine has 1 crank journal per 2 opposing pistons
a Boxer has 2 crank journals per 2 opposing pistons

Big difference in movement

V engine

----1<< 3
2>> 4----

Next
1>>3----
----2<< 4

Boxer engine

----1<>3----
-2>------<4-

Next
-1>-------<3-
---- 2<>4----


You CAN make a V engine 180 degrees flat or 120 or 80 or 170 or whatever.. as long as there's enough V to keep opposing cylinders out of eachothers space.

But you CANNOT make a boxer work as anything except 180degrees,
because at 179 they would not be able to turn over, they would bind
