The Wiseco rings in my 410(4.040" bore) are gapped at .022" top and .024" 2nd. They are steel top and napier 2nd rings. How much can I safely spray with that gap? I called Wiseco twice and got two different answers. One guy said 150 and another guy said 250.

For reference the ring gap chart listed this:

Street: .045" top, .055" 2nd

Street with moderate boost/nitrous: .050" top, .055" 2nd

Drag Race: .055" top, .060" 2nd (this is where my rings are set)

Race only nitrous: .070" top, .075" 2nd

I would say about 200 should be safe. 250 may be on the edge.

Thanks Dave. 200 is fine by me.
