I purchased a 1975 911S two weeks ago in San Diego after looking for a California smog-exempt car in good condition for two years. She’s currently running a 3.0 motor which reliably transported my fiancee and I back to the Bay Area in style. What a fantastic coastal celebratory drive home; even the portions of the drive that were in 104 degree afternoon heat through the San Fernando Valley and the South Bay Area (San Jose) were enjoyable.
The sale included the matching numbers 2.7. I've spent the last year or so searching the internet for good information regarding hot rod builds on the 2.7 motor. I have both Bruce and Wayne's books.
The only missing piece was the motor, but all of that changed yesterday when a large truck delivered a pallet to my driveway.
Mostly what I am looking for is some encouragement from Pelican members who have been through this journey and any recommendations of any shops in the Northern California area that are renowned for reliable air-cooled work (primary for time-certs if necessary, shuffle pinning).
This isn't my first rebuild ~ I've been deep in a 1972 Datsun project for the last few years which included a full build high compression motor ~ but it is my first journey into
air-cooled territory. Most of what I've found online is the hoards of people recommending folks like myself to ditch the 2.7 build and go for the 3.0. Since I have the 3.0 in the can and running, my energy is going into the matching-numbers 2.7 (well, until I short-stroke the 3.0 later). The story here is that the previous owner drove the car from it's offload off of the shipping truck to his house, felt something was wrong, and swapped in the 3.0 from his 1974 project 911.
My guess is pulled cylinder studs due to the thermal reactors but the motor hasn't actually been pulled apart as far as I can see. She'll be on the pallet until later this week when the air-cooled engine stand yoke arrives and I can get her onto the stand.
Thus far the project plan is Mahle pistons/cylinders, Carrera tensioners, PMOs, backdated exhaust. Would love to hear what you all have done and what has worked/is still working in your builds.
Many thanks,
