It might be an 1100S motor. You know, the 1100 motor out of a Mini S.

If it's a 1275 with side covers, it's either a Cooper S block or a Clubby GT. 1275LS didn't have side covers, but they did have a breather on the timing cover and another on the flywheel housing. |

Haha... I've seen a 1275 auto with 998 number, Cooper S with 850 number. Somebody might have had a 1275LS and their motor blew up... I'm not condoning this approach, just pointing out it does happen. |

interesting,it definately has side covers on the motor, this is what got me thinking it was odd that it has the 12h902 engine number. could there be a bit of funny stuff going on ? i take it that`s what you`re alluding to dr mini cheers jayson |

It may not even be a 1275- send us a pic of the block, from the front... |

A photo showing the engine number pad would be good. You can cover the numbers if you like for privacy. |

It's not uncommon to have the extra head studs drilled and tapped. |
