James,
whats the CC on the Z heads? where did you get them pistons from? what
makes them a turbo piston?
hows about this for an easy build: L18 block/crank(78mm) and L16(133mm)
rods giving a .85PDH, a 39cc head would give about 7.5:1, a 42cc 7.3, or a
45cc for about 7:1, only 1770cc tho.
just a thought anyway!
Paddy
