You are probably seriously lean up top, I have tuned some bolt-on F-bodies that touched 90% IDC. On a 408 I tuned for a buddy, I put racetronix 38#ers in there, they will flow 43lbs at 58psi, and his runs 73% IDC at 6500 rpms.

you can definitely hurt the motor. it'll get too hot being so lean. hope you didn't run it in the high rpms for a long time. that motor is starving for fuel. pump and injectors ASAP!!
