the coil ` box and wires are all you really need .. i have always ran stock dizzys with mine .. you will love it ...

And one more thing - wires are probably more important. Good 8mm with silicone boots are a must. It's amazing to see the "spider webs" off the wires in a dark garage. Wires are a relatively inexpensive maintenance item every couple years.

To be honest, I think where I'd see the most gains from the multiple spark with my set up is at lower rpms during cold starts. While my car has decent street manners with 10:1 compression and a fairly mild roller camshaft (241 deg Intake / 246 deg Exhaust duration @ .050” and .558" Intake / .566 Exhaust lift with a 110 degree lobe separation), it's old school with a 750 Holley, no choke, aluminum heads and a 160 thermostat, it can be a bear during initial starts in cold weather.

Yes, really. I'm always open to learning something, even if it's only somebody else's opinion.

I installed a 160 thermostat to help keep things cool during the summer and avoid any preignition, during the summer it'll run right around 180-190, maybe even around 200 in heavy traffic; we have hot summers here in Arkansas. I do have a choke, it's a manual choke hanging on my shop wall; I own five vehicles and the camaro is not my daily, unless the weather is nice. Yes, you could say I laid down on that one. I'm running 10w-30 dino oil in it and I don't drive it unless I'll be able to get it up to operating temp. Like I said before, I like the idea of a multiple spark at lower rpms and I want the rev limiter, but was interested to hear any negatives from using this kit on an HEI distributor.
