I have a 78 460 with 68 heads that have been ported with oversize valves. the engine has been balanced. it has a wieand high rise intake, a holly carb that has been rebuilt to an 875 cfm, 655/655 cam. roller rockers. it started once for about 40 sec, we shut if off and haven't been able to start it again. i put new plugs in it again. (may be a problem, might not be hot enough no one seems to know how hot i should get) it has an hei distributor. the starter is an old one off another truck, it doesn't spin very fast maybe this my problem?
hopfully someone can help i am getting fustrated! thanks for the help.
