    LS truck coils

    I just purchased a Holley Dominator ecu, and now I need to pick some coils. I know the Holley, AEM, IGN-1A, etc. coils are the best, But I don't know if I want to spring for them.
    Does anyone here know which GM/Delco truck coils are the hottest ones to use?
    D585= round w/ heat sync
    D514A= round (delco)
    D510C= square (melco/mitsubishi)
    Thanks, Steve

    you want the d585 coils with heat sinks. Search on ls1tech for more info on them.

    The triangle truck coils also work well(581, but the 585's are a bit better i hear for severe duty use.

    I have used the 581's and 585s at 800whp with no issues to date. good spark at 25psi boost.

    These might interest you-the price is right!!!

    I bought these for my project as I needed 12 of them- and here's what I have left over-a few if the pieces might have been used for mock-up at one point or another- But basically new stuff.

    These are not Chinese Knock-off that are now floating - be careful like on eBay...

    Down to one set of 8- GM LS2 LS3 LS4 LS7 Ignition Coils OEM 12573190 Round Style

    $130 shipped/set (conUS)

    2 sets of 8- AC-Delco 5146 plug wires

    $30 shipped/set (conUS)

    I wish I would've seen these a few days ago! I just picked up some used d585's, but with unknown miles/age. I will keep these in mind.
