I think the question focused specifically on the Holleys used on later GT350s.

The Autolite carbs used the dashpot.

After chatting with Tim, it appears the Holleys also used the dashpot and the photos are representative of the dashpot used.

Great guys I am making progress!  I purchased the dash Pot Tim pointed me to.  Now I need a bracket.  I found the bracket shown below on MAC's Auto Parts.  Does this look correct?  Does anyone out there have an original they would like to part with?

Now a few more fine detail questions.  What hardware is used to mount this bracket to the carb?

Finally in Kevin's pictures of the autolite carb there is a spring used.  Is this spring used on the Holley?  If so any idea what this spring is or where to get one?

Thank you so much for the incredible help.

Corey in the first 2 pictures you posted that i sent youin the beginning of this string of the dashpot on my car, there is not exposed spring like on the autolite.  I suspect that the spring is underneath the rubber boot

[Corey Bowcutt]

Kevin,

I am referring to the spring shown below.  Does your Holley have this spring?

[KDunne]

Corey, No mine doesn't have that spring on it

[Corey Bowcutt]

Thank you Kevin.

Can you tell if your bracket looks like the one I posted?

That spring has nothing to do with the dashpot. Its for the arm.

Late to this topic, but including a photo of the correct '68 500 dashpot and bracket.  Notice the bellows does not have an external coil spring.  Ford complicates this part by continuing the part # (without changing the engineering revision suffix) when servicing the "long arm"/plunger version that was used on CJ and B9, etc.

Now, the question of 350 application and tranny---I have not studied.

I've wondered too - why does a 4-speed car (as stated in the opening post) have a dash pot?  I thought those were only used on automatic equipped cars, were they used on later (after '67) 4-speeds?

Don,

Thank you for the picture it is very helpful.  Your bracket looks similar to the one I posted but not identical.  So if anyone has the correct bracket or know where I can get one please let me know.

Thank you all, Corey

hi per Tims request here is an early autolite dashpot photo

Which carb number?

[68blk500c]

Corey:  It stands to reason that the dashpot and bracket should be the same for a 68 Holley, regardless of 350 or 500.  The relevant dimensions of the carb would be the same.  I looked through my pictures of original cars, but didn't find a shot that will help you.

Can I ask, what was the purpose of the dashpot?  Was it to prevent stalling of the engine when letting off the throttle abruptly?  Why would some models have one but not others?  Thanks!
