White post restorations where forced to install a govenor on one fire truck engine restoration. It was obvious that over it's lifetime it had blown up several times previously.

They could not determine why so it got a govenor to keep the revolutions really down. That early block was very large. They got it as it had blown again at some point in time.

.I think that restored early fire engine is owned in virginia by a fire station company. White post did the whole restoration as well. Gold leafing and all. It had set for years or decades before the restoration.
