The Commodore station wagon was called Voyage. And the Commodore (as we know it in Europe) was put out of production in 1982, so I would say Mikuni is right.

I really enjoy this project. Don't deny the roots, go for the Opel grille! OT. I had an Opel Rekord E2 -83 (the weak facelifted twin) once, and damn I miss that car. They're getting pretty rare here, so it's hard to find a new better one...

I think it's just a stroked up B230/B234 from the 240/740 series. The head is the same as in the cars, the only great difference being the crankshaft and pistons. IIRC, if you're going to put the marine crank in a car engine, you need to grind out the block a bit or else it won't rotate freely. And somewhere close around that place is an oil channel...
