query re:  the '63 Spyder air cleaner housing (black vs. chrome)  thread.

<Hi  bill  
you  can forward this vv. 
When  trying answer questions on what is correct for a given year, use the 
resources  already available for research, namely period parts books book 
and assembly  manuals.  
In  my parts book dated oct. 1, 1963, and revised jan. 1, 1964,   
The  62-63 air cleaner unit is part # 6418069. This would have the 
crankcase vent  tube nipple, and would be considered the service part for both 62 & 
63.   
The  1964 spyder air cleaner is #6419148.  
The  assembly manual for 1962 indicates spyder air cleaner as 5648783. This 
would be  black one with no crankcase vent tube provision.  
Assembly  manual for 63 indicates air cleaner is a 6418069, no revisions. 
This would also  be black, but with the vent hose nipple The crankcase 
ventilation sheet in the  63 book has a release date of 7/20/62, so that’s pretty 
much just in time for  1963 assemblies. 
Assembly  manual in 64 indicated air cleaner 6419148, also no  revisions 
As  for 2nd question, the “special crankcase ventilation equipment” was  
RPO #242 for corvairs to be delivered in California . there is no sheet in 
the  manual for RPO 242 with RPO 690 (spyder package), only a sheet for  the 
standard 2 carb corvairs, and no sheets on rpo242 within the rpo690  
breakouts.  
I  would have to look through the 1962 order forms and see if any mention 
is made  of rpo 242 with rpo 690; it is possible the spyder was exempted from 
the  California vent system requirements, just as it was in 1966 (no air 
injection  with turbo). I just don’t have any more time to look up stuff 
today, there’s a  shop full of broken corvairs waiting for me.  
For  concours, our postion is 62 and 63 spyder air filter housings are 
painted black;  64-66 are chrome.  
Trivia-  for 67, there were no engines at the beginning of the model year 
that used a  chrome air cleaner lid, as the 140 was initially dropped from 
the option list.  Chevy must have had a bunch of chrome lids still left over, 
so to keep in  specification and use up some leftover parts, chevy painted 
them black and  installed them on regular 95 & 110 engines. I get these cars 
in the shop  every now and then, and when I see a scratch in the lid paint 
with very shiny  metal underneath, I tell the customer to try some paint 
remover for a nice  surprise.
