This says it come in both 1.5 and 3.0 ohm versions, so be sure you know what you are getting.

PerTronix 40011 Flame-Thrower 40,000 Volt 1.5 ohm Coil
40,000 volts
Available chrome plated or black for that stock look
For use with inductive ignition systems
1.5 or 3.0 Ohm primary resistance values available

While it’s the perfect coil to go with the PerTronix Ignitor breakerless ignition, our 40,000 volt Flame-Thrower canister coil can benefit virtually any distributor type inductive system. Its higher voltage allows largerspark plug gaps for added power, smoother response and better fuel economy. These coils are internally resisted so installation and wiring is drastically simplified. Our oil filled coils offer great heat control for street driven vehicles, while our epoxy filled coils provide superior winding support for high vibration environments in off-road vehicles and boats.

I don't think it will output any more voltage than the plugs require under a given set of conditions. Increasing the voltage about what the compoents are designed for will lead to arcing. So I would stick with the stock plug gap.
