I weighed both blocks this morning, and discovered that the ?TR6? block weighs 
about 11 lb more than the GT6-only block.  The primary difference seems to be 
that the cylinder walls extend about 3/4? deeper into the block to accommodate 
the added stroke of a TR6, and the related casting and webbing.   Don?t want 
the extra weight, so I think this block will go back on the shelf for the day I 
build a TR6 motor.  They must have made a running change at around the time the 
GT6 late Mk II or when the MkIII was introduced to standardize parts across the 
model range.
