Plug gaps & Pentronix ???

A couple of us are considering adding a Pentronix ignition along with one of their Flamethrower coils to our 352 & 390 motors (street usage - old TBirds).

We are interested in whether anyone has experimented with the plug gap under such conditions and how wide you have been successul at?

The assumption is that not only is a fat spark good for a variety of things but also that a wider gap complements it.

I have emailed tech support at Pentronix but gotten no useful information in response.

thanks !

Re: Plug gaps & Pentronix ???

you'll det to about .045" then start to get a miss at high load / revs. it will work great with a .038"/.040" gap. make sure you have good leads! cheers
