What have you got for a coil? points or electronic ignition? What gap did you have the plugs at? Fouled out right away you say - idleing in driveway? The carb, what is it like? new, rebuilt, set up close to right? Did the choke open?

Generally, try to start with plugs close to what the original car came with with that engine or one similar. you can go a heat range or 2 either way and chekc the plugs after a few miles, after the engine has warmed up.
