Al,

The engine pictured is a spare-part replacement case, a 911SC I think.
Those crankcases do not have stamped numbers.

You can get an idea of what a crankcase is using the casting numbers and the casting date.

For your ’76, there is a large difference between a 2.7 911S crankcase and a ’76 930 Turbo crankcase.
I doubt the ’76 911S engine had the original case replaced with a spare part for a 930 Turbo.

IF, your crankcase, crank & rods, P&Cs, heads, etc. were all replaced with a 930 Turbo, that is both good and bad.
The ‘bad’ part is the possibility of having 6.5:1 CR and no turbocharger.
The 'good' part is the 930 parts are more robust.


I thought I had an image of the engine (serial) number and the type number – I don’t have one in my file.
Search Pelican – there are many examples

Best,
Grady.
