The Giulia GT Veloce (1600 "GTV") and 1600 Spider (Duetto) shared identical
motors (Tipo 00536), producing a claimed 125 hp SAE/109 DIN. The earlier
Giulia Sprint GT (motor tipo 00502) was quoted as making 122 hp
SAE/106/DIN. The difference was attributed to new heads with changes in the
inlet ports (actually smaller, I believe).

The Super engine was quoted as making 112 SAE/98 DIN. I'm not sure what
accounted for the power difference, except that early Supers (up to chassis
no 86xxxx) were fitted with the early 101.21 head as on the Sprint GT.
Compression ratio was 9:1 across the range and cams were the same. I
*think* it amounts to different carb tuning <shrug>...
