My 440 dart I picked up seemed a little flat on bottom,it pulled ok but not a big tire roasting monster, I start checking it over yesterday and find that there is absolutely no timing advance, there must be a hole in the vacume diaphram because you can draw strait through it with a mightyvac tool plus the whole advance plate inside the distributer is siezed up,I couldnt even move it with a screwdriver,got a new distributer on the way:thumblef:hopefully bI will se a performance gain!
I wonder how much of a gain I will get!

If the entire assembly was siezed, I would imagine that you will see a huge gain. Is it possible that the previous owner had the vacuum and mechanical advance locked out and was going with all of the advance 100% of the time?
I see your from Maine. Are you going to the Atlantic Nationals in Moncton, N.B. this weekend? If you are, a few of us will be there on Saturday and some on Sunday.

I dont think it was locked out on purpose,it was all corroded and its quite crusty inside,its not timed with any real advance,,well its at 8btdc,I wont be going to the mopar nationals,If I would have know about it sooner it would have been a possibility

I'd say the increase in torque will be noticeable, as in night & day! A functioning vacuum advance will help your gas mileage by 1-2 mpg.
Wow wow holy sheeeite this thing is a bear now,popped in a electronic conversion deal,mopar performance looks like a stock electronic dist,now it will roast the rubber until I decide to stop,all through first and all through second feather off into 3rd and it starts to go!!!!I was a bit dissapointed at first with this car,my last car was a 67 chevelle with a LS-7 454 I figured the dart would be as quick but with the bad dist it wasn't even close,now I would say they are really close!

What did you set the timing to?
What's the specs on the engine.
I don't ever run the vacuum advance on my car, just use the mechanical, and I pull the heavy advance weight out so the advance comes in earlier.
I run a total of 36deg timing on my 440.
