| -3- Now will you write me something about pistons ? Particularly, do you cam grind and if so how, and how accurately ? New V.8 manifolds are arranged with single intake ports and a duplex down-draught carburetter in two H's thus :- Did you see the De Ram hydraulically loaded friction shock absorber ? Have you tried it and what do you think of it ? (Sgd.) Maurice Olley. We think that Olley's information about the American trend in pistons is exceedingly interesting because they seem to be following the Aerolite type of design; i.e. they are insulating the pressure faces of the pistons by means of saw cuts, and transferring the heat from the crown to the gudgeon pin bosses by means of inside webs. The net result of all this is that they are able to do away with the split skirt. We think that we could with advantage modify our semi-split design to incorporate some of these ideas.
