Engine technician. I recently discovered on my 2007 ZO6. THere is the name of a specific technician that handl built my motor! However the technicians name that is stated on the data plate is simply SALLY . And viewing other Vette owners Data plates usually give the technicians first and last name . So my question is simply this was there a engine technician that when he / her was finished assembling the motor used the name SALLY ?
