Is the allison the same in the LB7, LLY, and LBZ engines? If so, can you put more power through a LB7 than say an LBZ since the LBZ already has 350hp and 650ftlbs? I have an 02 and my PPE is on the 90HP setting, can i put it on the 120HP setting with the stock tranny as long as i stay clear of a hard 4-5 shift?

Yes you can. BUT it is almost impossible to stay away from the 4-5 shift. if you accidently get it to kick down it is all over. See my sig

With the LB7 you should be safe with the 90 IIRC.
