Many pages back, there was speculation about the first slider pipes on A Konigs. Anyway, A Hydro was won by Armand Hebert, running one of the new aluminum-block A Konig motors. This short-lived version got a new crankcase and 34mm carbs that were used on the later and much better-selling and more successful iron-block, single pipe A Konigs. And it had slider pipes. Whether this engine was entirely new for '68, I can't say.
I have a block from one of these aluminum-block A motors (I'm betting most of them got replaced by the later iron blocks). A rather wierd piece, it has pistons ports with channels to single phenolic reeds, as do the iron blocks, but in this case both the piston ports and the case-reed ports run from each carb to BOTH cylinders! Each cylinder is thus trying to draw its intake charge from BOTH big 34mm carbs. I happened to visit Ron Anderson's shop when he had just sent off one or two of these by-then-obsolete aluminum As he had gone through for Dave Mayer in California, and observed to Ron that the engines had to be massively over-carburated. Ron said, yeah, they seem to make nearly the same power with one carb disconnected (or so I remember, 35 years later).
