Ok, so a little history for the un-initiated:
Way back in the 60s, Triumph decided to make a larger V8 powered sporty GT car than they ever had before. This car was known as the Triumph Stag, and it used a unique OHC V8 that never appeared in another car. When Saab caught wind of the V8 development however, they approached British-Leyland about a slant 4-cylinder OHC engine based on that architecture. This engine made its way into the early Saab 99s, and the Triumph TR7/Dolomite Sprint. On Triumph's side this engine fizzled out with Triumph, but Saab continued developing the basic Triumph block for years.
When I say years, I mean it. Saab's final development of that architecture went out of production with the 9-5. It went from 1.6l to 2.3l, gained eight more valves, direct ignition, turbo charging, and some of the first adaptive engine management software on a production car(Saab's Trionic). At the heart of all this though was a Slant four that Saab got from British Leyland in the mid 60s.
Ok. If there is some commonality, then it should be possible to move some bits and pieces back and forth between the Saab B-series and the Triumph. What I'd be curious about in particular is an SPG powered TR7 or Dolomite. The Saabs used a distinctly different engine mounting system than Triumph did, but if the basic block is the same then this COULD be as easy as fabricating an oil pan for the bottom of the Saab engine(or maybe even using a Triumph pan), using some of the Triumph accessories and mounts(alternator and such), and mounting the whole shebang up to the Triumph transmission.

I think it'd be a hoot, if it would work. Anyone have any ideas?
