Need a cam advice

[HPICamaroSS]

I have a TR224 on a 112 LSA in the 6.0 in my big truck(99 1500 ECSB 9" lift 37" tires). I also have a 10.5" 3400 rpm stall converter. Runs great, ran a 13.0 on 31" tires. I will say that the 224 does fall off on the topend above 6k rpm.

Would you go a different route?
