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 |

The machine work on a mag case adds 3k to the rebuild over an aluminum case
Thus should be calculated into the comparison to a 3.0/3.2 motor Lots of places can do this work But machine work is a paid skill |

Anybody have an extra 3.0 case in their back pocket. thanks always |
