Distributor question for 400
Will a distributor from a 302 work in a 400? The wires going to my distributor had the insulation melted on them due to a fire caused by a fuel leak. I have one in a 302 but don't know if it is worth the trouble to swap them . The 400 starts up fine and runs okay but has a slight off idle miss to it. I have recently refuilt the carb and put new plugs and the plug wires all look good. It has good compression on all 8 cyls and the vacum is 17 at idle and steady.. Maybe it is timed too slow. What are the timing specs for a 400. Example Static-centrifigual-vacum advance .... Todal degrees at 3500 RPM? I am eventually going to put a new cam gear and chain without the retard build into it.... Thanks...

If you decide to get a new distributor, consider our custom curved Duraspark Distributor built with our new Full Length Oil Impregnated Bronze Bushing. The full length bushing improves timing stability and spark scatter. If stock appearance is not an issue, take a look at our one piece D.U.I. Distributor. Whether you choose the Duraspark or the D.U.I., we curve each on a distributor machine based on your engine combination. Please see them at<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com
