Thanks willwren - I'll take a look at that thread.
I know I've been quiet for a while - been busy at work as well as busy working on the car
old engine is out, new engine is in and almost everything'* in place. I've got only about a couple of hours of work before the first start attempt - I'll tell you all how it went.
As to the engine replacement work, everything went pretty smoothly. The only big annoyance was that the old engine came from a Buick LeSabre (I found that out only after I bought it), so it didn't have the oil-level sensor on the oil pan. So I had to swap oil pans between the two engines and that was a bit of a headache.
I ended up removing the entire exhaust manifold before lifting the engine, and installing it back only after the engine was back in. Surprisingly it'* not much harder to remove or install the exhaust manifold while the engine is still inside.
Anyway, thanks for all the help - I'll be back with updates soon
