Hi, I have a 547 ford stroker that I have just bought a Zex dominator 100-300hp kit for and I want to know what spark plugs you think that I should run? Does Zex make a nitrous plug for the 460? I couldn't find one on the list. The motor is still in the build stage, but I'm aiming for at least 600hp on motor using 98 ron pump gas. It has SCJ aluminium heads and 10.1 comp. Ignition is Crane hi6tr (timing retard). Not sure of any other info you would need. Thanks.

All of the info that I have tells me that we do not have a plug for that application. If you can get the dimesnions of the plug you are using now, or a part number, I can try to cross it over to make sure. Other than that, I would recommend contacting Autolite or NGK and see if they can recommend you a plug a little colder than stock.
