* is the truck de-mandated?.. or is all the emmisisons systems still operational and in tack?.

* Also, with 3.25 rears, no matter how much HP you put into that engine .. as soon as you put it under a decent load.. it will feel sluggish and weak. Those 3.25 rears are horrible. My car does not even have rears that tall. It would be a much wiser investment to replace those terrible rear ends to make it pull better than to try to over-work the engine and shorten its life. Putting a set of 3.79's in it or maybe even a set of 3.90's, it would pull almost 2x better and feel like it had some actual ballZ again. This without even changing the power on the engine yet. - just saying.
