(And while things were a bit lax on emissions inspection, at least through the '90s, one of my old customers looked me up about a year ago--a two owner '76 930 trying to keep his near concours car road legal here telling me how tough it is just to meet tightened down tailpipe standards now. I think he wants to be last man standing with numbers matching, original 930 3.0.)

So, in the end, how does said 930 stay on the road, in CA, legally? I know there are other ways, but wondering what recourse may be through a referee, or something.

Not sure, and doubt "they" care. If you've got the car 100% as-delivered, spend the $400 (or whatever) to "do something" mechanically. If it still doesn't pass, you'll get your ONE TIME waiver from the referee. After that??????

.. and the budget part is the issue .. i new 3 guys who had 2.7s at som epoint , all 3 ended up with three litre motors after reviewing the costs to "bring back" a strugling 2.7.
if i could get someones 2.7 core locally though i think it would make an excellent coffee table ..

A couple of years ago, there was a bill up for approval to move the cutoff up 5 years-it got little press, and I'm surprised the automotive focused businesses, clubs, etc in the state weren't all over it.

Ah, but the slamming above had to do with a '77.............. Being in lovely Oregon, I don't THINK you ever had to deal with one needing to live its service life with thermal reactors, an air pump, and EGR. And likely no front oil cooler. Oh, don't forget dealer/port added A/C.
My only point was that a properly built 2.7, sans all that emissions equipment and some modifications, is a genuine delight to drive, and can be just as reliable as any other 911 engine with proper oil temperature control. Its simply not inexpensive to do.

But were you putting them back together 100% stock? I had to really educate customers about the what's what of mag case longevity in a CA smog world. You'd get REALLY good at ensuring exhaust stud/fastener health, as it would be two short years and a car would be in twice for the thermal reactor swap. Pretty much an at least once-a-month deal, given how many '75-7 cars would be in your customer base. (IF you were lucky in scheduling people, and this was long before the bar codes on the door jamb VIN..........let's say maybe the same car got smogged 2 or 3 times????)

Given the draconian Oregon emissions laws, we had no choice but to leave them stock. That said, we did remove the thermal reactors for some lookalikes that did nothing and install a front radiator-type oil cooler on ALL of them with a fan. Richened it up a tad for road use and they lived.

The thing i like most about the 3.6 swap into a 911 chassis is the torque, it's always there no matter what gear.
I agree that it was much more attractive to do the swap back when relatively fresh 3.6s were available, the first one I did was in '94 w/ a 6k mi '93 964 engine. Still even if you need to rebuild or refresh a 3.6 it's going to have a ton more snap than any smaller engine.
I'd even go for a 3.8-4.0 in g50 car.

I'll be happy to report the results of my 3.6 swap which should be ready to fire up as soon as i get my fuel lines from Lenny.I pushed my 3.2 pretty hard but a 95 SW chipped 3.6 with lightweight flywheel and pressure plate in a car that also lost 200 lbs of unwanted body weight should be interesting to say the least !
