69 Camaro L48 Flint or Tonawanda or both?

I am looking for a casting number and date correct engine block for a 12C built Van Nuys 69 Camaro.
Any chance a 3932388 block stamped T1209HB would be correct?
Thanks

I have a friend with a LA built 01B ss/rs with born with drive train. 388 block. Tonawanda....Joe

I would say that is a good match for that build. Both Flint and Tonawanda blocks were used at Van Nuys
