64 Valiant 426 ss on craigs list???

This car is not too far from me. Do you think it's worth a drive by?
He has a few other roached out rods and a small lot.
I am not familiar with b/rb engine codes or where to look on the block for them.... if I can even see them. Any tell tales I should look for?
I just finished mini tubs on my 63 so I am curious to see how & what was done.
$6500 is a lot but.............If it's the right stuff...........FIRST DIBBS! lol!
Thanks for any input! & don't tell my wife you saw this!
