Re: alfa-digest V7 #1128 - VVT Cam Correction

[AlfaNeely@domain.elided]

    Sorry, but the intake cams in my 82 and 84 spiders both have the 
centrifugally operated advance mechanism.  My 85, 87 and 91 spiders are all 
operated by the solenoid.  I have considered putting an early cam in a later 
spider and just plugging the hole where the plunger fits through the front of 
the cam cover.

 The 1980 Spider did indeed have Variable Valve Timing, but unlike 1982 and 
later cars, the 1980 and 1981 versions had a purely mechanical form of 
variable valve timing.  They appeared the same time as the mono-butterfly 
version of Spica.
 
 When Alfa switched to Bosch FI instead of Spica in 1982, the VVT became the 
electro-mechanical version more commonly seen.
 
 The '80-'81 version appears to be retro-fittable to earlier cars - it's all 
contained in the intake cam drive gear assembly, which does require a cam 
cover with a taller front section.   Whether or not you'd actually want to is 
debatable.
