Mk 1 has a thin flange and M2 the thick flange (where the block meets the gearbox). |

And very early Mk1s reputedly were weaker around the centre main. |

Some early Mk2 Cooper S's (my Mk2 is car number 336 and it has the thin flange block) also had the thin flange block but with the 9F/XE/Y engine number and reportedly some late Mk1's had thick flange blocks. Probably fair to say that sometime in mid 69 there was a transition from thin flange to thick flange blocks - nominally around the introduction of the Mk2.

Keep in mind that the /SA/ refers to the gearbox type, 3 syncro and /XE/ refers to gearbox type 4 syncro. I have also seen a lot of XE thin flange blocks but cant recall seeing a SA thick flange block. Not that it didn't happen, possible I guess. |

The thick flange MK2 block I have has a stiffening rib adjacent to the dip stick hole. The question is: Do all thick flange S blocks have the stiffening rib? RonR |
