I can't wait for the research to get back on this one Greg!!
It is an awesome stone.

Speaking of big CAIs... Here is a rather nice 1cm plus CAI from a new CV3 I had classified. (still provisional at this time)

Here
 is the "CAI stone", which came from another group of NWA carbonaceous 
stones (not the same as above and still under classification). This one 
is on its way to Germany for research and study (may be the largest CAI 
ever!) but is still nice to look at. I am excited for the results of 
this one...

I have CM, CO, CR and CV that all have CAIs visible.

Simple answer: any kind of chondrite.
However, most common in carbonaceous
chondrites, particularly CV's. They contain
more refractory elements than the "ordinary"
condrules they are found with. They were
formed at higher temperatures and many
show signs of repeated meltings. They are
older than the next most early solar system
materials, the chondrules, by 2,000,000
years or so. Two different dating methods
give ages of 4567 my and 4571 my.for CAI's.
