Can someone please advise me on where this hooks up?

Leave it open/as is & you'll be fine. I have put a gas line filter on it to filter any debris that might make its way inside but that was on a dirt track stock car & not sure if it'd be needed in a DD especially as I think the vent valve is only open at idle live every 24 hour block of time like it's your last day on earth

I now have come across another problem with the throttle linkage. The new carb is slightly different and hits on the intake manifold. Here are some pics. I can only post one at a time so bear with me. 7600013-oldlinkage.jpg (56 downloads) 2016 Diesel Ram 3500 Mason Dump 1971 Challenger 2013 Jeep Wrangler 1979 Dodge Ram Power Wagon 400 Mini Pumper My other car is a Fire Truck.

My air cleaner rubs on my hood insulation now, I don't think I have an extra 1/4" to play with. 2016 Diesel Ram 3500 Mason Dump 1971 Challenger 2013 Jeep Wrangler 1979 Dodge Ram Power Wagon 400 Mini Pumper My other car is a Fire Truck.

Can you please include the tuning instructions you told me about on the phone? or maybe you could email me those.

If you're using an open element air cleaner what about a slightly shorter element & Scotts spacer?

EDIT or a drop base air cleaner I have to use the stock air cleaner cause I love the wrinkle finish and I have an all stock look. Could I just cut off that little elbow that is on the new carb and not on the old carb? 2016 Diesel Ram 3500 Mason Dump 1971 Challenger 2013 Jeep Wrangler 1979 Dodge Ram Power Wagon 400 Mini Pumper My other car is a Fire Truck.

As far as the area that it is hitting, it appears you have a 71 vintage cast iron intake or similar? The area the linkage is hitting is the boss for the idle stop solenoid mounts, if it's just hitting that roll pin you can remove the roll pin and it might clear? If not I'd wait on modifying the linkage until after you try the spacer, after that if it still hits we can revisit it and find a way to fix the issue, shouldn't be a big deal.

ScottSmith_Harms Mr Wizzard Joined: Jan 2003 Posts: 42,714 Spokane Washington	Yes, that is correct. If you are restoring a 71 340 car to factory specs that's the spacer you need. The factory only used those for one year, an aluminum spacer about 1/8" thick sandwhiched between two multi layer foil/asbestos flat gaskets. I make reproductions of the aluminum plates (inquire for pricing) and commnly available paper replacement gaskets will work in place of the obsolete asbestos variety. These were replaced in later years with several styles of thick paper/cardboard gaskets (which I'm sending you unless otherwise instructed) which are still available and work just fine if all you need is proper linkage clearance and 100% originallity is not your goal. 7600737-thermoquadgasketstogether2.jpg (55 downloads)
