5.3 Vortec coils
 

I run a 5.3 Vortec in my 64 short step and want to hide the coils under the Holley 2 piece covers. They will not accept the coil packs that come on the truck motor. Can I swap out all the coils with some modern ls3 coils or will my computer not like it?

You could try the coils from a 2002 Camaro. They are different from the later coils.

The Holley covers only work with D580 or D510C coils. What are the Camaro coils?

If you change coils, are the plugs the same?...seems like I've seen somewhere they had to change out those as well
Why not just use the coils Holley says?
I bought a set of edlebrock coil covers only to find my coils wouldnt fit...they bolt to the covers, I assume the Holley is the same..I wound up not using them and made my own covers

My original question was can I use a different coil, like one of the two designed to fit the Holley covers, or will the computer not like that.
