@Matts440 i may have a complete set of gm d581 coils I’d ship to you if you’d like. I have a partial (I think 6) set of d585s. You could have them for shipping cost. Give me till tomorrow and I’ll know what I have.
Factory “good” coils are a non issue. I make about that power on stock gm coils. Hell Richard Holdener made 1530+ hp on stock coils. When tuned correctly (dwell time) and wired correctly they’ll be just fine.
I totally agree with the factory coils, don't think Louise went with factory being he was doing a budget build when he did this. I appreciate the offer, but he mounted the coils to the valve cover so the mounts for the d581 are different. I'll get some of the MSD ones coming here soon. I only had my dwell set to 3.5ms. Let me know about the d585 I can get the extra two that's no biggie. Thank you my friend.
