    if youre future plans are too go forced induction ,s/c etc go with the lq4 lower compression if not then the lq9 is a badass motor higher compression .you should be able to tell by price if youre getting fromsalvage yard.lq4 comes in hd pickups,vans,example .lq0 comes in escalade ,and ss pickups.i personally have lq4 for f/in .hope it helps .sorry i dont have numbers,i did the same swapso any thing i can help with let me know.
