The hotter coil won't do anything if you aren't changing the plug gap, etc...If your distributor is high end, aftermarket, etc, it might be worth it. You would then want to adjust the gap most likely. If the distributor is stock type, I'd just use a stock type coil. If you are going to use the stock plug gap setting, there is no advantage to the high $$$ coils. You only need the hotter coil, if you are going to use a wider gap. If you use the stock gap setting , and the hot coil, the performance will be the same as stock. Any more voltage *over* what is required to jump the gap is wasted. Or to put it another way, you only need as much coil, as to jump whatever gap you have. So if you use a stock plug gap, anything over a stock coil is a waste of money. Or thats the way I see it anyway...Others may differ....MK
