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 |

I've rebuilt a few mag case 911 engines. The machine work on a 2.7 isn't going to be cheap. Line bore, Deck height, case/head stud inserts, oil bypass mod, don't forget to do an insert in the Intermediate shaft case through stud as well. Not needed but dowel the mains too if you have the means. Ollie's did all my 2.7 case machine work. I'd have to look for my receipt to see what it all cost but that was also 16 years ago. Here's their price list : http://www.olliesmachine.com/uploads/ollie..._March_2019.pdf I had all that done on my 2.7 case when I built it up to a RS. Pm or give me a call about it. |
