Excaliber, Thanks for your input. You have certainly given me a clear explination on principals and a good starting point to super tune my timing. I am not sure at what my dist. is set at but it's a Mallory Unilite not a MSD. Are the pre-sets similar comming from the factory? And how will I know whats under the rotor...are the springs and weights identifiable as whats stock or modified. I don't know what the other guys mech. did to tweek my engine. What I am finding is not impressing me as to his knowledge. Thanks John
