I will always try to include a 3 to 4 wire upgrade in such a service change, however if we would like to delve into the NEC:
250-140's key word is 'existing'
250-142(b) EX #1 states; The frames of ranges, wall mounted oven, counter-mounted cooking units, and clothes dryers under the conditions permitted for existing installations by Section 250-140 shall be permitted to be grounded by a grounded conductor
Ok, so tape that puppy up & off to the N-bar!
BUT WAIT !
90-5(b) Permissive Rules nice if you do it, but don't gotta!
Ok, so on to the G-bar???
Art 100, Special Permission; basically what Tom saidSo can we do a poll of AHJ's here?
Door #1--Noodle Bar
Door #3--rejected until a 4-wire set-up
