Mystery Engine, figuring out what this is Options

[lapuwali]

So, I just bought a nice running engine from nine14cats, who'd bought the whole car with engine from Craig Laughlin, who'd gotten at least the engine from someone else. We'd been told it was a 2.2, and it has carbs (Weber IDFs, not Dells, as previously thought), but that's pretty much the extent known. Has three-bolt heads on it, but no engine number I can find.

I measured the stroke down the plug hole with a welding rod (works better than a chopstick...), and it comes up 76mm. With a 96mm bore, that would be exactly 2200cc, so it looks like it really is a 2.2.

Before installing the engine, since I'm going to do one easy valve adjustment, anyway, I'd figure I'd trying to measure the cam by just measuring the height of the rockers when open and closed. What's the lift on the stock cam? I don't have a degree wheel, so I doubt I could do better than +/- 5 degrees trying to measure duration.
