Got an 83 Ram Charger with a 440 today!

Like cuda mark said earlier, the intake is probably culprit as the vacuum leak can cause hairpullin bad carb-like maladys. Take the intake off and get it iether magged at a machine shop or have them check for cracks with dye. I believe all the cracks can be fixed with Devcon "steel" epoxy putty. But you may have to disable the egr functions. Another option would be a 440 edelbrock performer intake. Other things to check is having the correct base gasket as the thermoquad gasket is different than the Q-jet gasket (just slightly but it is enough). All the hook ups look ok but think the choke might be hanging up or bad/misadjusted.
