Yeah stock is 30 to 35 thou.

But how much gap you can run is totally dependent on the whole ignition system, the better/stronger the ignition system the bigger the gap. To the point where the holden commodore with the (chev) 5.7 has a coil per plug and spark plug gap of 1.4mm...thats pretty big.

I'd go with a .045" gap and see how see runs. Bigger spark that way.
