    .007 ?
    you do realize thats .007 times the bore diameter right?

    example if its a 4.25" bore its 4.25 x.007=.030 MINIMUM RING END GAP

    I think that's absurdly too tight for a 500 hp shot of nitrous on the ring gap.

    Id suggest something closer to .0095 per inch of bore diameter.

    Id at least call and talk to several ring manufactures and nitrous kit suppliers and get their thoughts

    That sounds about right, that's 0.040 for the ring gap. 500 shot of nitrous is a lot of nitrous!
