Breaking in the rebuilt 2.7 in my '76 911.
Took it for a 50+ mile drive this morning. When I got home the odometer is showing 160.
So far, all is well with just one minor oil leak around the oil pressure sender (I think that's where its coming from). Engine is running better and better as it breaks in.
After rebuild it's a little over 2.8L with new everything.
