A 10k motor is every Spridget person's dream. 9k seems to be about the
most the racers can get without very serious work, rwad EXPENSIVE work.
You will blow more than a gasket at 10,000 rpms, more like blow the
engine apart.
The heads are interchangable between 948s and 1098s but the 1275 has
it's own head.
Yes the bores are the basic difference
