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.

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: "Mark Lindahl" <mplindahl@xxxxxxxxxxxxx> 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 __,_._,___ |
