spark cutting out at 6300 rpms

the car in my sig,

all new opti,8.5 msd wires,msd coil. my rev limiter is at 7100 rpms so its not that but feels the same

1. i know i am running too cold of plugs for the street
2. i dont have a ignition box

if i put in the ar12's that would be right for the street and got a crane hi6r you think it would solve my problem or am i going to have to ditch the opti and get a alternate setup

I was never good at troubleshooting from a distance. But I can say that you don't need to ditch the Opti. I am still running one and an MSD6 and have no trouble with spark up to 7,000rpm even under boost with nitrous.

Check your valve springs,it could be valve float.
