Real ACDelco coil at a good price
I don't know how to tell a great coil from one that just "does the job" without cutting it open - and I am not cutting a new coil open just to have a peek. So, I am relying on two things when I give this coil a 5 star review. First off, for the same price as my local parts store wants for a no-name coil, I bought a real ACDelco coil and ACDelco has a good reputation. Secondly, I bought one of those no-name coils (because I needed one in a hurry) and weighted the two and the ACDelco was 1/4 pound heavier. Does that matter? I'm not sure but it is a clue that this coil might be better built.

Best coil for the money so far
Bought to replace old coil in a 66 GTO. Came in perfect condition. Installed it and so far it works fine. Will see how long it holds up. You may need to adjust the bend diameter on factory coil bracket as these coils are slightly larger diameter than the original.
