Here is what I was thinking as far as mod list for my truck which is an 04 GMC RCSB 5.3
Texas Speed Longtubes
Volant intake (I know it can be done cheaper, but I like the looks of this one)
Trick flow 220/224 .575/.575 112 cam with applicable springs etc
Circle D 278mm 3200 stall (Recommended by Chris there)
Corvette Servo
Sonnax 4th Servo
Aux Cooler
Shift kit
Texas Speed Tune
Any input?
