68 GT350 4 speed dash Pot

[Corey Bowcutt]

I have noticed in photos an item on Holley carburetors that I do not have on mine.  I have been told it is called a dash pot.  I have a February 12 1968 GT350 4 speed with the aluminum intake and Holley carb.  My question, should I have one of these on my carb and if so does anyone have any available?

Thank you, Corey

[Corey Bowcutt]

Excellent! Thank you Charles.

I would respectfully disagree, I think both of the the S8MS Holley carbs were equipped with a dashpot (4spd and Automatic)

[TLea]

Agreed. All 68 Shelby carbs used dashpot

GT 350 uses same as GT 500 set up
Don, you got a pic?

You guys sure?  I have examples of both.  My '68 (2152) was judged at several MCA/SAAC nationals over the years and never had a deduction for a missing dashpot.  I went back through the judging sheets to be sure.  MCA judging sheets don't mention the dashpot though.

Tim, the big block dashpot has the long push rod, right?  In the examples I have a small blocks with a dashpot, it's the style used on 65-66 automatic cars.

Well this is interesting.  So to my second question does anyone know where I can get one that is correct for my car including the bracket that mounts it?

[Coralsnake]

I know of a car that went through SAAC judging and was painted the wrong color. It never received a deduction. None of the codes were changed.

Not surprised on judging. Until I really researched 350s about 8-9 years ago there was not a lot known out there about 350s. Sure everyone knew 500s and KRs but the 350s nobody had really seen many that were done correctly. Regarding the style of dash pot, when you say longer pushrod you're thinking of the cobra jet carburetor which is true on a KR. The 6566 used a autolite style which is a totally different Dash pot and bracket. 6 68 350s and 500s had holley dashpot with a rubber boot around the plunger. If you look at 68 GT 390s you will see the same style used. Let me see if I can find a picture

Found a picture, I asked 'Pete to post it since it's from his collection

Bracket is what's hard to find

[CharlesTurner]

Is the belief that only 4sp Holley carbs should have a dashpot or also 4300 4sp should have one?  I found a reference noting for the 4300, a dashpot only applied to auto trans cars... and was like the earlier cars except with a longer shaft and slightly different bracket.

Guess I'm not completely convinced, maybe some original photos/low mileage examples would help?  Any documentation? 

Pic of the bracket would be nice, I have several, but they're all mixed style.

OK picture of autolite 4 spd dashpot coming
