Bought a 80% done project. 1.7 engine has been rebuilt and lots of new goodies installed. However I don’t know what heads, and internals were installed. Engine has never had oil in it and looks like jewelry with dual Weber 44s, new heads and powder coated tins. I’m on a quest to learn what I can about this new engine. Other than the carbs, only other info I’ve found is a number 850910 stamped on the heads next to an intake port. Any recommendations on how to learn what I have without taking everything apart?

I have a similar situation. Someone put a lot of time and energy into the motor on my '70, but never ran it. I have no idea what is in there, but I suspect it is not the stock 1.7, since it is setup for Megasquirt and the car has a side shift trans. I doubt he went that far but kept the stock bore. I'm gonna pull the heads to measure bore size and valve size. That will still leave me in the dark regarding the cam, but I don't know what I can do about that. Would be nice to know the stroke as well. I imagine that can be figured out with the top end off. On 911s you can tell the stroke by the rod bearing size.
