Bob,
6= 6 Cylinder 911 1= 911T 1=1971 0455= sequential number. The "3R" is a casting number, one left half and one right half. Basically this is a magnesium case from a 2,2T. Any other questions? What is the "Typ" number?

Bob,
"Cylinder outer base diameter to crankcase" 2.0 92.072-92.159mm (checks with spec book p. 27) 2.2 same as 2.0 (checks to spec book p. 39) 2.4 same as 2.0. It's only when the 2.7 cylinders appeared that the diameter went to 97.072-97.152mm, or a 5mm change, basically. So it is possible to build a 2,4 on a 2,2 case, I believe the distributor bore is larger on the 2,4 case, which would require the use of a 2,2 distributor.
