    Exclamation 69 buick MsD

    I installed a 69 Buick 430 in a 70 leSabre.
    I switched to a1975 HEI ignition an now i am wanting to add an MSD or upgrade to a more powerful coil that output approximately 45 KV.

    Why? .. it seem that i am not burning all of the gas supplied to the cylinder.

    I had the block bored 60 thousand, added an elderbrock 750, added the elderbrock intake, added comp 469 cam, modify oil system and i feel that the firing needs upgrading.

    Which coil do i need (if i need one),
    What model number MSD do i need that will work with what I have?
