If you are running a high enough quality of gasoline so there is no engine knocking using a locked advance has some advantages. Low end power is increased, drivability is improved and you eliminate an area of potential problems (distributor advance). If you have a high compression motor(10-1 or higher) you may be forced to run a mixture of racing gas or you may have detonation issues. Remember, you cannot always hear when your motor is detonating so it would be a real good idea for you to use a 95+ octane mixture with your locked advance if you have this kind of compression. Also, if you have any type of cooling system inadequacies a locked advance may exacerbate the problem. You should have a starter retard or you may brake your starter drive if the motor kicks back as is the tendency with motors with locked advance without the retard feature. -Bob
