2000 TC Engine number

Where is the engine number located? I found this online Engine Number and was surprised that the TC had both 9:1 and 10:1 CR. I thought they were all 10.5:1. Can anyone verify this information as well as the engine number location? I'll be looking at the car I might buy again today and I'm trying to be as informed as I can. Still not sold on it but leaning toward yes if the price is right.









 
The engine number is on the top of the block, at the front, on the LHS as you look from the front of the car. Just below the big round plug that gives access to the timing chain tensioner.

Thank You! Looks like they did come in 2 CR's based on this Rover Classics I just found. Since this is a Federal car I'm assuming it will be the lower CR since our fuel here for the most part had a lower octane rating, but I could be wrong. Maybe it being a '66 and one of the first to come here it might have the higher CR. I'll know in about 2 hours.
 
What year is the car? It will be 10:1 up to mid-68ish. There is now way of telling from the engine number. I know that list says 415 engines are 10:1 and 416 are 9:1, but I have a 416 engine that is 10:1. That said, I don't know the history of that engine other than it came out of a 68 car, so maybe it was retrofitted with 10:1 pistons at some point.

10:1 engines have a sticker on the side plate that says 10:1, but that sticker is gone on 99.99% of the engines.

It's a '66. That 1st link I attached says if the engine number 415 it's 10:1, and if it's 416 it's 9:1. I'll see what I can find soon. I'd like to get a compression test as well but my gauge broke a year ago and I never bought a new one so I hope the owner has one.
 
My '74 2200SC has the compression ration stamped on the head next to the engine number, which is where Harvey says it is, although his picture appears to depict a 2200SC.
 
Engine number is 415002, so apparently 10:1. I decided not to buy the car because of several reasons. It's a solid rust free car but needs a retrim, rear brake work, radiator, all the rubber trim, carpet, etc. I still think it's a great car but the price is too high when you factor in the work and parts needed. I'm in no hurry, and I know of another for sale, but it's more than a days drive away, so I'll try and find the time to check that one out. Thanks for your help everyone.
 
With the cars now being so old, you can't be sure just judging from the engine number. My current engine has a 416 serial, but has been rebuilt with 10:1 pistons.
The only way to tell for sure is to look at the pistons, either by removing the cylinder head (unlikely) or the sump (easier).
 
You realize you passed up owning a very, very early TC. That engine number is missing a couple of digits, but even if they come after the 2 there that car was in the first couple of hundred TC's built.
