The two 413’s I have with four barrels on them carry the 3251 model carburetor . Joe, are you sure you have a 383 and not a 413 engine in it. The one 62 Sport Coupe I brought from an estate in Missouri listed it as a 383. But one of the pictures I saw, showed a four barrel carburetor. When I got the car I looked under the hood and checked the block top under the power steering pump. The top on the block was flat and had 41 stamped on it. The 383 engine had a place above the fuel pump that had 38 stamped on it. You may have a 413 engine and not know it. Both of my 62 Sport 413’s came with dual exhaust. One was a 3-speed manual transmission, the other an automatic.

It is a 3251S.. The car also has dual exhaust, dealer installed a/c, and a PCV valve. I am only the second owner of the car and believe the carb to be original. (Maybe dealer added when he installed A/C.) I think I saw a choke heat riser spring on ebay recently. Good luck, Joe On Thursday, May 7, 2020, 06:38:33 PM EDT, 'John Grady' jkg@xxxxxxxxxxxxxxxxx [Chrysler300] <chrysler300-noreply@xxxxxxxxxxxxxxx> wrote: Agree totally with Ray…AFB runs ok, but always seems to be under 15 mpg. AVS was from emissions period, much tighter overall quality control , Edelbrock gave it a performance tune—smart –probably partially motivated by hassles with AFB. ; Thermoquad even better, but they are like Rochester I believe, two small and two huge bores. __._,_.___ Posted by: "Jerry Lindsay" <jerrylindsay300h@xxxxxxxxxxxxxxxx> 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 https://groups.yahoo.com/neo/groups/all/manage/edit 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 __,_._,___ |
