    You should be fine and should be able to go 150-175 with no problems as long as the tune is good.

    as far as timing goes you are going to have to have some way to adjust it if not it will lean it self out when you hit it i mean factory setting is 10 so i would go with 8 and run it there and set it and make sure it is set at 8 before you go shotting any shot of bottle to it

    I can adjust the timing but the advance is locked out so whatever i set the timing to is the total timing is what im asking. I was thiking starting around 24* - 26* with a 75 shot

    That is a good starting point 24-26, and you should be fine, 1 range colder plug cap it down a little.
