Re: [Chrysler300] '63 300 Torqueflite mount specs





Isn't Mark's car a 300 Sport?
I thought it was.......
3256 is a normal single 4 bbl Carter application.

Hi Mark,

 

Even if the linkage moves, pedal will then move, ---not the carb end. ..carbs still sit on throttle stop screw, at minimum for idle, held there by return springs ..is anti stall dashpot on it? Not that it works great, but it helps.

 

I was told once that mounting carbs sideways makes them more fussy about momentary fuel slosh direction in bowls , so flow in idle jets impacted more by fuel height over screws. Momentary high level = momentary rich mixture.  I think all 300 ram cars tend to stall easily at factory correct idle RPM (and sometimes then won’t catch!..must go rich, =wet plugs?) . Not sure of rationale for any of that, prior are my own thoughts, but definitely fussy. And of course have to be set up right on car ..many are not…all screws MUST be open same amount, if undamaged screws/ seats. Edelbrock new AFB replacement screws cure a lot of “Carb” problems. Stock screws can get a ring around them from hours of carb diddling over 55 years, makes it act kind of on-off instead of smooth adjustment(unknown to you!) . If you see or feel raised or depressed wear rings on taper of screws get rid of them.  A carb that was inoperable on idle became perfect with new screws for me. Raising idle helps, but then a jarring TF engage. I am not sure there were ever “loose” converters for iron TF. ..But 300J fixed that on 727. Check exhaust heat flow in /under carb (the restrictor game in warm climates) . Present hi test gas here has alcohol, evaporates faster, heat aggravates it ..and aggravates all these issues . M! any rams came off when new over this kind of thing…..why gone for 62. But back with manual choke in 63-4… Can work great, but not a trivial task to get them right.

 

As in hot day in 4th of July parade…..it stalls ,won’t catch… auuugh.

Forgot to mention that I had an extra 3256S Carter AFB, so I had it rebuilt by Jim McGowan (Quad Shop).  The stalling problem happened with two different carbs, so I do not think the stalling problem is related to carb float adjustment.  Both carbs work perfectly under most conditions.

Hi All,

 I suspect that after I had my 413 and Torqueflite rebuilt, the person that reinstalled the transmission may not have torqued the mount bolt sufficiently.

 When the 300 was recently on the lift, the spring between the transmission mount and the transmission seemed to be extended a few inches.  When the mechanic lifted the end of the transmission, there seemed to be almost 3+ inches of vertical movement.  This seemed excessive to me.

 On a side note, I am still having a problem with stalling as I slow down and take a sharp right turn.  What I think may be happening is the engine/transmission may be moving/tilting in such a way to affect the throttle linkage position?  Tell me I am crazy, but that’s what I need to investigate.

 What is the spec to tighten the transmission mount bolt?  Once I do that properly, I will know more.  I checked the shop manual, but I could not find it.  Thanks for all ideas.

 300ly,

Mark Lindahl

’63 300 Conv. w/413
