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 |

My Ollie’s bill was closer to $4k for my 2.7, and it got all the works including oil bypass, decking, inserts, and a twin plug conversion. Running it with a Solex cam and Webers. The 2.7s are wonderful engines when built, as the make more HP than my stock 3.2 with a Steve Wong chip. I think their bad rap is due to the emissions crap which retained excessive heat and caused the warping. Shops would just torque down the heads and covers making things worse.
My 3.2 is sure fun with all the torque but the sound and performance of a 2.7 - can’t wait. Plus it looks way sexier than my 3.2.
