Carl, Roger and all,
This is what I found on the Giulia SS cam cover variants.
Cover #1) The initial Giulia SS cam cover and listed in the 101 Giulia catalogs as #
105.00.01.510.02 . This is probably Roger's SS engine's cam cover. Listed continuously untill chassis 380058 and then 'on and off ' untill car 381396. I haven't found this cover on other 105 cars except of on the 105 TZ, therefore it is not so common I think.
it has no dips for the air intake hose, no breather pipe or extra bolts at the front.
Roger's cam cover becomes more and more interesting, particularly for checking whether it has a moulded number at the inside.
Cover #2) From car 380059 on, and alternating with the 105.
00.01.510.
02 cover #1, but definitely from car 381397 on, Alfa mounted the
105.02.01.510.00
This cam cover had the dips for the air intake hose and was also mounted on the Giulia Spider Veloce and the early 105 GT without breather pipe. The ones I saw don't have a moulded number at the inside. Still no bolts at the front !
Cover #3) The ultimate Giulia SS cam cover:
105.02.01.510.01. This cover had the breather pipe at the front, still no extra bolts at the front. It is also listed for the Giulia Super ( ... probably it has the two dips too, I couldn't find an exclusive drawing of this cover, sorry.
There was no starting SS chassis # given for this cover, but the data was coming from an amendment from 1966, so very late !
For the relevancy, Fusi lists car 381399 as the very last Giulia SS, that was anno1965.
The main problem is that we have no details about how many pieces of cover #1 and / or cover #2 were mounted during the alternating period ( 380059 <> 381396)
Rgds,
Thierry
