Hey Gary, I know that your combination was deeply thought out but IMO its asking alot of your engine with that much stroke to be spun that high. If your running NOS I really don't think you'll need to spin it that hard to run 8.50's. NOS engines work better if they are "lugged down" meaning less timing, lower rpms, higher rear gear ratios. Doing this will take full advantage of the torque provided by the NOS. Hey its your call so please don't be mad with my suggestions but I'm just throwing some things out there for you to think about.
