Any of the Classics CAN be very good rifles. The early ones with 5 digit SN's were pretty much all very nice rifles made before about 2000. Starting around 2000 is where the 7 digit SN's start. Many of those are every bit as good as the early ones, but there are some with issues too. Especially the closer you get to the ones made in 2006, the last year of production.
Can't say for sure about 270, but I have a 5 digit SS Classic 30-06 that as near as I can tell was made in or near 1994. It has a 22" barrel. I know later guns had 24", but don't know when they made the change.
