I have asked this over at .org as well, but want you guys opinions: Existing daily driver is 1997 Ram, Club Cab, 1/2 ton, 2wd, 360, 5 Speed and 3.55 gears. 15-16 is consistent MPG even with Scan Guage and efficiency modifications, and good driving techniques. I am going revive the Dart Lite, and use her for what she was made for...MPG's. I have a budget of $500.00 to $700.00 for tweaks to get her back. Here is what I have to work with right now: --76 Dart Lite. 225, with alum intake, 1bbl carb, stock exhaust manifold, 2-2.25 exhaust with Dynomax "welded" muffler. --4 wheel drum brakes in small bolt pattern. Stockton 15" ralleye wheels with 235/60/15 radial tires --3 speed manual transmission --2.94 gears in 7.25 axle --No smog parts whatsoever. --synthetic fluid in both the transmission and rear end. Engine leaks too much for synthetic. See next post for basic needs.
