This are kws at the motor though. Take 25% off minimum plus wear for KMs and it won't be that high.
I did a before and after of a stock V6 with the 3.89 diff gears and a T5. Was 136 rwhp in shootout mode uncorrected an then 182 on the same dyno with the new motor.
New motor was +1mm oversize pistons , .020" off heads and small bowl blend with a 201/207 @.050 cam with .470" lift and a set of headers.
It did a 100mph pass at 14.8 with a lot of wheel spin as I'd taken the locker out for the insurance inspection and sold it with an open diff. New owner took it to whoop ass Wednesday. They then fitted another locker and ended up doing a rod bearing on the pad.
