1973 911 RS 2.7 original block - trying to find its car.

I guess the seller needs to decide if he is willing to sell this case to anyone at an agreed price. The depth of knowledge here by other posters is impressive.

Looks like the case saver machine work took out 99% of the cylinder base sealing surface.

Just catching up. All good questions. Many of the series numbers posted look a lot more pretty for sure. That said I have also seen some wonky looking real serial numbers on blocks that have never been touched, they were all hand stamped. Even the horizontal scratches I have see on a few simply from cleaning and scraping with wire brushes, wire wheels, etc. to clean decades of crap off a metal case. These engines were, for a time, not worth any real money (which is a shame). To grind off a number a re-stamp it means shortening the boss that the stamping is in by the depth of the original stamp plus a little. I wonder if there is a measurement of that boss thickness from the factory?

I will get a pic of the type number. The seller was there when it was taken out of its original car. As to John Walkers comment, as I understand it that case was never machined. I will ask that question though. How would I determine if it had been?

For the record, I get nothing for this if it gets to the right car. Just trying to help a friend out, and reunite a car and its block. The guy who has it is someone I trust though.

Good observation John Walker. I think 100% in one case.

Probably why the case was replaced.
