Almost, the spec for 2.7 is max difference in weight of the set is 6g, that's &#177 3g

There are 9 weight groups for the con rods all are &#177 4.5g

Starting w/ the '78 SC for Mahle they speced 4 weight groups for each market, all are &3177 2g for production pistons but &#177 4g for service(repair) pistons. Similar arrangements for the KS pistons.

It' really interesting to note the weight difference between the ROW Mahles which start at 668-672g and the US/Japan Mahles which start at 636-640g
