Flat air cooled 12 for the 914?, Wonder if this will fit.... Options

An example of a flat -12,somewhere between the extremes.
Bruce Crower in America built a turbo flat eight in 1976,methanol fueled,for USAC(Indy).
Lind in Sweden has built a type-4 8,The Brazilians Marco and Arlindo have done it to a type-1.
Looking at the pix of the engines,it is clear that twelves can also be done with similar methods.
Some custom parts have to be designed and made to fit,ie,the cases,crank,cams,heads.
Using the 94mm(3.7") cylinders of the 2L T-4,and a 66mm(2.6") stroke crank,a displacement of 350in^3,is achieved.
Using the bore spacing to T-4 dims,the crank has fewer mains and a shorter length.
Pushrod heads,6 X T-4 heads,welded and silver-soldered together,a huge engine.
A lot of work,and requiring the moderate lengthening of the wheelbase,~200mm.

Build your own engine,just like Ettore Bugatti,and the Wright brothers,35 years before.
To some of you,it's a far-fetched dream,while others are working on such fairy dust,made of metal.
Climbing mountains makes people 'feel something',making metal feels something too.

Note the case stiffening plates Lind has installed to carry the cylinder bases on the Eight.
I believe he has plug welded the original stud holes,then,welded the plates for a secure re-machining for the studs.
A taller deck height,solving case spigot discrepancies,and the thin-wall die-castings.A perfect solution.
He has also welded up the plug holes,then re-machined for smaller,angled plugs.
