Engine Numbers
Ok, The engine in my 71' has the engine pad milled smooth. My hunch is the block was repaired or replaced in the past. The heads on the engine are correct. The car is low miles: 45K.
Why this important is I am buying parts for the car and I have already run into a harmonic balancer issue. I ordered a 71' which is an 8", and the one on the car is a 6.75", and the timing tab will not clear an 8".
Is there a number anywhere else, or is there a secret police type way of extracting anything off that pad?
Any help is appreciated.

If it was me, I would get the part number for the block off the back of the block, driver's side. Then, I would get the casting date from the back of the block, passenger's side. Based on that information, you should have a pretty good idea where the block came from. If you don't have the common books, just post the numbers here and folks will help you out.

Well, no way without taking some things apart, but if you want to know what is in there, you could get a good start on it by taking off the oil pan, yes? You should be able to see what crank is there. I have never done it, but it seems like you should be able to get a micrometer on a cylinder from underneath and get an idea if the block was bored. I think that, and figuring out what heads you have on there, is a pretty good start to knowing what you have. It still leaves the question of the cam open, but if all the other stuff comes back stock-type replacements, I would guess the cam is stock too. Of course, you could always pull the carb and intake....
