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 |

So there's billet aluminum ($12.5k) and billet magnesium cases ($?) out there. Interesting. Can see it for racing applications, less so for street cars. Next one I do will be mag case, and there's something to be said for keeping a case that came out of Zuffenhausen once upon a time, even for a mere six conversion, but one does begin to wonder: What's the life expectancy of the base metal in a 50yo mag case? |

Pretty sure that ITG small bore case pictured above is aluminum? I've been following his thread on Pelican. Would be interesting if it were mag ...
Mag cases are needing more work in general. They're fragile, and 2.7L motors were hard on them due to heat and pulling studs. The 7R cases (late 2.4 and 2.7) are considered the best from a structural perspective if you can find one that hasn't been abused. |
