72 Duster Resurrection

A jiffy kit for these carbs is super cheap. Looks like a holley model 1920. I can rebuild those in my sleep. Slants will run on shitty gas. A friend of mine ran his one time on varsol and laquer thinner for a week, though i wouldent ever recommend that. I would recommend using a bit of loctite on the carb to intake manifold studs and carb mounting nuts as i have had them work loose on a few slants i have had.

A quirky thing about these is the distributor drive gear. Its nylon plastic. After you get it up and running i'd recomnend pulling the distributor , taking it apart to clean out the spiral oiling grooves on the dist shaft. By now they are prob coked up. Cleaning them up and applying fresh oil will prevent the shaft from locking up and breaking the gear. Also i recommend dissassembling the distributor and clean and lubricate the advance weights. they use bronse bushings on them. Also remove and clean the timer shaft that the rotor fits on. Theres a felt pad in the hollow upper part of the shaft under which is a snap ring to remove it. Every time you do a tune up your supposed to put a few drops of motor oil on the felt pad under the rotor so that shaft stays lubricated. Its prob all sticky by now the grease being close to 50 years old. Then get a new nylon drive gear from dorman (help section) it comes with a new roll pin and thrust washer for about $10.

Mopar made the distributor gear on slantys out of nylon so if it broke it wouldent wipe out the cam. Theres plenty of slants with plastic distributor gear pieces in the oil pans that are happily running around out there so its not a big deal.

Other than a few quirky things, an engine is an engine. Check to make sure the vac advance is working, and make sure none of the vac lines are cracked. Mopars slant 6 or 30° inline. Isnt much different than any other inline six. The reason for the angle was they wanted it to be able to clear lower hoodlines that were being penned in the styling studios that a regular straight six wouldent be able to do.

Congrats on the duster. Hope our wealth of knowledge helps you out. We're glad you found us. This is the best place for mopar A bodies in cyberspace. I'm sure there will be a build thread on this in the future. Will there eventually be a V8 in it? Or are you planning on staying with the /6
