    well this was supposed to be a poll of what initial timing ppl with a stock 250 are running, but I couldn't figure out how to do that lol....... so what are you guys with the 250's running as your initial timing? If you have done mods significantly affecting your timing setting please specify; if you would be so kind. Reading up alot on this and wondering how much of a variance there is between everyone's car. Thnx guys, maybe this will be fun haha:clap:

    You do realize that initial timing depends completely on how much mechanical advance is built into the distributor, right?
    You can only have about 38 total advance (ignoring the vacuum advance) on the engine so if you have 28 in the distributor you can have up to 10 degrees initial. If you have 30 degrees in the distributor then you are limited to only 8 degrees initial.
    Find out what you have in the distributor (the advance mechanism is stamped with numbers of DISTRIBUTOR DEGREES) and then set your initial timing to make 34 - 38 total. You will have to double the number stamped in the distributor to get crank degrees.
