Not a lot of progress. Will be fixing the cracked exhaust manifold This week, and finishing the exhaust this coming weekend. Should have all manifolds done and mounted. Then can start on carb spacers, linkage, and fuel line plumbing. Mounted up my refurbished heater lines, and made some small stainless tabs to keep the copper one from sagging. Almost done with air cleaners, changed them up a bit.
Not much for pictures, exhaust is almost done. Will get some pictures soon. Intake is near being done. Working on finishing the plumbing, and starting the linkage. Exhaust manifolds are finally done and free of cracks. Will be raping the pipes soon!
Kool shit! Wishing I could have gotten out and seen the progress with my own eyes but work work work!
Such a cool car! Just saw this thread for the first time but enjoy seeing the car on Facebook. Wonder how many folks don't know each others real vs. HAMB names?
Steam cleaned everything, mounted all the manifolds and heater lines. Set up some fuel lines. Exhaust is 90% done. What is done is painted. Need to finish exhaust, carb spacers/linkage one fuel line and a vacuum line. So close.
A suggestion based on experience, get a couple of 1/2 inch phenolic spacers for between the carbs and manifold. Also when you set your float levels you want to set them a couple 32nds lower than factory. This will go a long way to dealing with high temp fuel perculation and hard hot starting. Also make sure you align the slots in the carb gaskets with the passage that feeds manifold vacuum up through the carb body to control the step up Jets. Without the vacuum signal they default to wide open providing an over Rick mixture resulting in stumbling, plug fouling, and excess gas burning.
The pictured gasket has 4 slots in it so it can't go on wrong. Some depending on source have one slot and some have no precut slots. Remember you will need a gasket below and above the spacer block if you use them. The vacuum path in the carb is a small hole in the base. With the slot aligned high manifold holds the jet closed at idle and steady cruise. When you accelerate or climb a hill vacuum lessens allowing the spring to pull a tapered rod out of the enrichment jet in proportion to the load, until intake vacuum is restored. Look closely at the pic of the riser you can see the slot that feeds the circuit. So the blocks need correct positioning so the slot is toward the carb
The spacers also help align the throttle linkage at more favorable angles if you are using rods not cables.
This car looks like something that might have been used for "running 'shine". That little bit of polished copper tubing along the firewall helps to reinforce the illusion.
Nice find on the old Mopar! I'm glad to see the old 6 stay in it, and your choices of minor mods, rather that cut it all up. Edmonds did make a head for those, but they are scarce.
Really like your approach to this beautiful classic. One of my favorite body styles(all '39-'41 Mopars) Drivetrain mods are amazing. . Incredible craftsmanship. Hope you don't destroy too much of what Detroit got so right. Saw one of these for sale many years ago. Was smitten by all the cool art deco styling cues.
I’m sure. But has no heat risers in exhaust manifold. And the factory setup was an aluminum one. I think it should be fine.
Always nice to see another Mopar being worked on. I'm typically a fan of the mid-thirties Mopars but your 40 looks great.
Finished the exhaust today. Turned out great thanks to the help of my buddy at Kell Kustom. Started on the carb linkage. Should be running in 2 days. Seriously cannot wait.
