Continuing the investigation, and still yet to make a choice!
Having cleaned the mud and goop from the original motor it appears OK, no broken castings from storage and no rods poking through the block. As I said, it is not seized, and appears complete. It has been fitted with the wrong carb at some point, but I have what I suspect to be the original carb in a box of bits that came with it. As I also have the original bellhousing, it would seem that I have all the parts required to return to the factory spec. should I choose to do so.
So, the big question! I've never driven a 2L Series 1. Obviously power is less than a 2.25L, and quite significantly less than the Holden 186. But can it reasonably be driven on modern roads? With the overdrive engaged, and assuming everything is working well, can it produce a cruising speed that will avoid angering the truck drivers?
