.040 overbore? I thought those didn't like much more than .020" over. Looks pretty nice though pricey. -James |

0.040" over is the max on an aluminum block. This one's been bored to the max, meaning "end of the line" when this present build is worn out. :-\ |

Hard job especially with *thinwall* sleeves? Cheers, Wizard |

So what are the down sides of owning an aluminum 225? DO they have issues iron ones dont? Were aluminum heads ever offered? Pardon the newbie questions... I didn't think the price was too bad for what is there. |

The scarce 1961-'63 aluminum 225 has lots of issues the iron block doesn't. Block corrosion is a major issue especially at this late date. Parts availability (special head gasket, special rear main seal parts, and a few others) can be difficult. It's got freestanding bore sleeves (open deck design) that makes the top end a great deal more difficult to seal up reliably, even with the special head gasket — much lower limits on compression and other performance increases for this reason. Assembly technique is much more critical. It's not a bad engine when properly built and maintained, and of course it's fun to have something rare, but for most people the ~80-pound weight savings isn't worth the extra expense, hassle, and difficulty. |
