2.7 case rebuild
I have a 1976 911s 2.7 with 216,000 miles with the engine undergoing a rebuild and have just been told that the case is too tired. We have tried helicoils, then case savers and the head bolts are still pulling out. Because there was only one head bolt initially pulled, I have invested a substantial amount of $ on everything but the case. Now the foundation is discovered to be bad to the bone. The body of the car is in excellent shape so I would like to save the considerable investment that i have already made but decent 2.7 cases are hard to find. Can anyone recommend a machine shop that could find me a used 2.7 case, inspect it and install the case savers so that i can rebuild the engine on a proper foundation? Thanks for your thoughts.

Ollie's Engineering in Lake Havasu Arizona is real good with magnesium cases, however; I don't know if they could source a 2.7 case. For that you could post a WTB on the Used Parts Classified Forum.

The most ideal case for your use would be a case from a 73.5 T because the 2.4 never ran hot or stretched studs and the case tend to open up easily to a 2.7. The 73.5 are all 7R strength cases.

Or you could just avoid 90% of the problems and go with a later aluminum block. If you no longer have matching number , who cares.

Talk to Competition Engineering as well. They are certainly one of the best two/three shops in the country. But if I were doing my 2.7 over, and I went thru everything you did, I'd do a 3 liter aluminum block. Second best is the 73 7R case from the 2.4.

Just chiming in here... What is the advantage of a 2.7 over a bored 3.0, is it lighter?
Aren't there two different types of 2.7 engines ?

Call Ollie's they are experts with 2.7 cases. They most likely can fix it where others can not

This isn't the for sale section, but I just pulled apart a good 2.7 case with no pulled head studs. PM me if interested.
