Mark and all:
Carter used the “S” suffix on the AFB carbs to denote that it was a
complete carburetor “assembly” part number, vs. just an individual part like an
idle mixture screw. The additional “A” suffix after the “S” would indicate
some degree of engineering change to that particular model carb; so yes, in
theory, it might have some operational performance improvement, or could include
revised/updated parts for some component that proved troublesome in the
field.

AFB Hi
Carl, Thanks
for the suggestions. It seems like “trailing technology” is the best
bet. It is good to get comments from the experts! By chance does
anyone know the change that occurred when the 3256S went to the revision
3256SA? I can only assume that the SA proved to be the better performing
carb vs. the 3256S. Regards, Mark From:
Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of
'C Bilter' cbilter@xxxxxxxxx [Chrysler300] Mark, The AFB 3256 is the
correct 1963 carb for the 413 non-HP engine (i.e. FirePower 340hp) used on the
New Yorker and Imperial, and if I recall correctly your engine came out of a New
Yorker. I also recall you used a fairly mild cam, and so the 3256 should
be an ideal match to your engine. In other words, as I remember you
did not build a “Firepower 360” HP engine which was the factory optional engine
for the 300 Sport. From experience with three 1963 Imperials, I can
say that the 3256 provides very good performance and economy (economy relative
to 1963 expectations) when properly rebuilt. I see no need to go with an
Edelbrock which is roughly equivalent to the Carter AVS but is built
“generically” for a number of applications. The Edelbrock 1406 is the best
match but will require a ‘68 and up style base plate on the air cleaner, or an
aftermarket air cleaner, as well as possible rejetting and maybe a linkage
adapter. Why bother when you have the correct carb? I recommend Jim
McGowan in Rockford for rebuilding. Carl

[Chrysler300] Edelbrock vs. Carter AFB
Hi All, I am running a single Carter AFB 3256SA on my ’63
Chrysler 300 Conv with a 413. I have heard a suggestion to “upgrade to new
technology” and get one of the latest and greatest Edelbrock 4 barrel
carbs. The 300 is completely stock and that is what I prefer, but if the
performance and gas mileage would be improved, I may be willing to make the
switch. The 413 was just rebuilt in the last 3 years and is running
strong. Your comments are appreciated, especially a suggested Edelbrock
model that would be similar to stock. Regards, Mark Lindahl P.S. The 3256SA has been rebuilt by me. It
runs well, but I am pretty sure it would run a bit better if it was
professionally rebuilt. __._,_.___ Posted by: "C Bilter" <cbilter@xxxxxxxxx> To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to http://autos.groups.yahoo.com/group/Chrysler300/join and select the "Leave Group" button For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang __,_._,___ |
