What spark plug for 100shot nitrous

[340Duster247]

Hey guys just curious what spark plug (part#) I should be running on my 340 with eddy heads and a 100 shot of nitrous.
And what gap as well.

Btw the engine is just above 10:1 compression. Hypo kb flat tops.


Thanks a lot guys

Compression, camshaft specs,gears,transmission (a/t,stick),manifold and Carb type. Info needed. The crickets will sing.We need a band leader.That would, be you.

I'd start with an NGK R5671A-7 and see how it looks on motor alone. 100 shot isnt going to have a major effect on plugs if you have the right one to start with.

I just got r5671a-7s today. Now thinking about gap....
Details on engine are
340 40 over
Eddy rpm heads
Comp 497 lift.
Holley 750 dp
Eddy airgap
Tti headers
Msd digital 6
Taylor 10.4 wires
2800 stall
727
4.30 gear

Nitrous
NOS 100sshot plate

They come gapped at .035", and that's what I use. I don't think your going to find major gains there, and smaller (vs .045"+) will be safer on spray.
