Better understanding

[The Squires]

All,

I have been reading and studying the BB history and have a few questions:

1) As I understand it, all of the xxV71 engines are "V" in construction and
are 2-cycle. Is that correct?

2) I believe that I would really want to stick with 4 cycle engines. Is
the Cat 3208 a 4 cycle? I know the DD 60 series is 4-cycle.

3) From the used ads, appears that the DD60 series did not show up until
mid-90s and they seemed to be matched with 6-speed Allison's. Are this
facts correct?

4) In the mid-90s, I see quite a few BMC models. From there weight and
engine combinations, these appear to be cheaper BB. Don't want to insult
anyone. Is their construction the same "bus" standard or closer to the
fiberglass/paper M/H?

5) Do the PT, LX, & LXI have the "bus" construction with metal outsides?
