The first silver "big case" Picco 90 had drum valve.

#2 came with the same case but with a std disc rotor.

#3 had a zimmerman CF disc still the same case.

At that time the "hydro" 90 came and that was a "small" case 90.

#4 first of the "blue" head "big case" 90 engine came with a piston dia of 27,4mm.

#5 "blue" head "big case" 90 that was almost square in piston dia and stroke.

#6 first "black" case XP 90 engine.(possible to get it with silver case also)

#7 proto XP 90 engine with a crankshaft like a CMB.

That is most of the Picco 90 engines...........

Steve,

The "BIG" Picco .90 ( they were called the Competition .90 ) and the small block Hydro .90 had the same diameter piston ( 1.082 ) and all dimentions were the same except that the Competition .90 had a MUCH bigger wrist pin. I have some parts for the big .90 if you're interested. Email me at "[email protected]"
