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...

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.
All the coils are sold- Plug wires are still available-
