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? |
