[QUOTE="NTXRockr, post: 13855144, member: 143742"] I know the topic has been discussed ad nauseum about running upgraded springs for higher rpm and boosted applications...but what about nitrous guys? Does nitrous affect valve float/loft like boosted cars do, or am I ok if I keep it below 7700 or so??? I've been turning it to 7500-7600 but snapped a rod, and now am installing a Livernois 11.5:1 shortblock (coated diamond pistons, h beam Manley rods) and already swapped to a mmr oil pump gear. I previously ran a 150 shot but am soon going to a 250 on the Nitrous Outlet plate. Am I skimping by not going to at least the boss springs or Livernois springs, or can I run it for now and swap springs when I swap cams in the near future? [/QUOTE]
