Seeing as you managed to put that nice a car together for 6 grand or so, I'd say you are to be commended! It looks really nice. Sometime down the road, you might want to upgrade the exhaust to 3" mandrel bent tubes, which either means buying a kit from TTI Flowmaster, etc., or having it done at a good exhaust shop. An X pipe will bump the power up even more.
If you wind up with a over-heating problem, you could fab up a shroud and a rubber shield over the top to make sure the air goes through it. Check the trucks in salvage yards for the 7 blade clutch fan, if there's room. Usually found on late 360 trucks with the HD cooling option, think D350 work truck. I've found 2 in my travels, and have less than $30 US in both of them. You can find a lot of good stuff in heavy duty trucks....
If you have the .920 torsion bars, you should be in good shape, as these are a little bigger than stock equipment on 383 equipped A bodies. It sounds like you were able to avoid the problems my buddy had putting the 440 in his 69 Dart, which required some Z bar mods with the headers he used.
When the money improves, think about some Caltrac bars and maybe the springs. In the mean time, you can help out the stock springs by getting some bolt on spring clamps, andd clamping the portion of the springs ahead of the rear axle at every seperation. This helps control axle wind-up, and sort of makes the front of the spring act like the lower bar on a 4 link.
If you feel like further experimentation, take the clamps off the rear segment, it allows the rear of the spring to "fan" or seperate, and allows more chassis lift to plant the tires.
This varies from car to car, and if it doesn't help, just re clamp the rear of the leafs. You can either get a buddy to weld up an extension to for the pinion snubber if it isn't tall enough to reach the floor support area, or substitute a D series Dodge truck upper control arm snubber if the distance isn't too great, as they are taller than the stock rubber piece. Replacement snubbers for Lakewood traction bars work too. Usually these can be bought used at any swap meet cheap, just like greasy two barrel Chevy small block intakes!:toothy10: Keep the snubbers, throw the bars in the trunk for weight....
You are off to a real good start, both on the car and your marriage, here's wishing the best of luck to you on both!

Thanks
I know that this forum is a long one, with several pages, so I thought I would bring you up to date...
1. The exhaust on it is 3" mandrel Bent tubes. I didn't want the X pipe because I like the sound of the exhaust without it. i like how it pulses more, and because I am not makeing a race car, I don't see it of being any use.
2. The brand new Aluminum rad I bought has kept the engine nice and cool. the temp gage hasn't gone over 185 once! I don't think I will need a shroud, and I don't like the look of them, so i would like to stay away from them. hope I can, no problems yet.
3. My T bars are brand new performance ones, I posted the part number on here, and was told they were Big block ones. and if your buddie has any probles with 4 spd stuff, I highly recomend Brewers performance.
4. I don't know what Caltrack bars are, sounds like something for the track. If so, I don't think I need them, But I would like to know what they are/do?
5. My springs have been re located inwards, and have brand new leaf springs on the back, I think they are SS springs, but I could be wrong, I think I have the part # some where. These where installed on the car just prior to me buying it.
I'm really not interested in makeing this a Race car. More like what a 1970 duster would have looked like if it came stock with a 440 4 spd. I don't like the look of roll cages, or a race car look, on a car that doesn't really see the track. Don't get me wrong, this car gets up and goes like a bat out of hell. It just seams fine to me the way it is.
But...
If I am looking into getting better launch, or suspension upgrades, it sure sounds like you know your stuff.

PS. check this out. an older brother to my car is on Ebay (almost an exact twin). If it really sells for that much, what would mine be worth?!?!?!?!? some people are on glue.
Smaller engine, not the best year..auto..? over $14,000
