For what it's worth E motors didn't come along until 1969 when Porsche was using magnesium so technically speaking Porsche never made an aluminum cased E motor.

The interesting thing about you case is that the serial no. is from a 67' 911 because 67' coupe motors started at 909001 and go up but the Red Book shows that 67' coupes (excluding the S) came with motor type 901/06 which was the same motor basically as the 66' 901/05 motor except that the cams had decreased overlap for the valves. So my guess is that the early 67' coupes came with motor type 901/05 like yours before being changed during the production run.

Well I guess we may have found a new data point for the Red Book.
