On the other forum, someone posted a
notice for an Ebay 401 with a Ford 6 engine, which prompted some discussion. Among the chat was this comment:
"Prewar BMW blocks aren’t all that tough to find if you’re in Europe…and I know of a rebuildable EMW unit in NH that’s available for a reasonable sum. The 328 style head is the killer, though they’re available new at about $10K apiece. I’d be tempted to install more modern BMW based mechanicals such as the M42 4 cyl, which is almost exactly the same length as the original engine and would provide sufficient power to move the car smartly, yet not completely overpower the thing."
So, any comments about a BMW M42 engine fitting as a replacement? It certainly would be the right provenance.
