This 2.7ltr 911 engine was in my 1977 911s, it runs extremely strong but does have some oil leaks. I have checked the cylinder studs and all register ok with none broken or pulled threads. I used it every day as my driver and I was always impressed with how strong it was for a 2.7ltr. This is the last of the stronger reinforced magnesium blocks and is a 7R case, engine number starts with 627 with type being 911/85. My current car is going through a change and I do not need this engine anymore. It is not the original one that came in my car, I traded this about 6 years ago with one of my customers. It has a new fuel distributor with a new fuel pressure valve, new accumulator as well as a new warm up regulator, has a new intake boot with a intake pop-off valve and comes with the stock muffler. Will consider partial trades. Call or email me, cell 647-990 0959.
