The incredible power and torque of these engines as well as great daily driveability is something one needs to really experience to appreciate. Peak power is made at no more than 5750 rpm with peak torque at 4750 rpm. Don't look only at the peak numbers. As we keep drumming into your heads, it's the torque curve that makes the car accelerate and be driveable. These monsters have over 450ft.lbs torque as low as 2750 rpm. Tuned correctly and driven correctly they can also be incredibly fuel efficient in most conditions. There are many so called experts offering big power LS1 based combinations but no one will give you this torque curve, reliability at these prices...no one!
