Another thing you can do about the weight if you haven't already is replace a lot of the engine compenents in front. The 2 barrel intake, front timing cover, and exhaust manifolds are all cast iron and HEAVY! Replacing all those with aluminum intake, aluminum front cover from Summit, and headers will reduce the weight. I don't know what you have done to the engine, but aluminum edelbrock heads are also a weight reduction and major power increase! With my ranchero, im doing a lot of custom work. Im putting a 69 mustang front end on my 79, so im getting rid of a lot of weight. My original bumper had to be around 75-80 pounds. I also got rid of my A/C. All together the A/C stuff had to weigh around 100 pounds. Those are all things you can do. The more "small things" you do will add up to a big change. Good Luck.
