We are attempting fitting a 2.7 into our 1974 rustout hulk but have come across another hurtle. I have had a 2.7 kicking around for awhile and "assumed" we could go through it with new bearings/rings/..... and have a nice power plant. Not so quick there. The head stud issue is well known and I recently found when the magnesium cases are disassembled the crankshaft bores no longer return to a round/aligned condition.
I want to believe someone out there can get these magnesium cases in serviceable condition with good crank bores and good head stud bores. thanks |

numbers matching I suppose it's true, "anything can be saved", but at what cost and what value. We have been successful in the historic building restoration business for many years and can fix anything, but often it is less expensive and will provide better long term value if we replicate with new materials. From what I understand Classic Porsche has new cases, now we are really digging into our pockets. |

From what I understand Classic Porsche has new cases, now we are really digging into our pockets. If I have the story right, Porsche had some nos 3.2 engine case blanks that they had machined and sold. Now that they have the setup ready to go, it would be nice if they continued to make them. It's still not inexpensive once you add up all the parts to complete an engine but greater availability helps. It also helps to consider that while the cost of a rebuild isn't cheap, it wouldn't be unreasonable to expect the engine to last most of us for the rest of our lives. Most of us use our Porsche's as play cars and 2-3K/year is probably average. |

Our 914/6 may get 2k miles per year at best and if it lasts 50 years I will be 120 y/o |
