    just wanted to know if there was anyway of telling what year block i have?
    i dunno if it in the casting number that it will show it or if maybe there is a sensor for one series OBD block that there isnt for another.
    if it does help though the casting numbers on my GSR block read:

    B18C1
    0735110
