Excellent feedback guys, I appreciate it......... all roads are pointing to LS7 as that is what I have always wanted. So its time to do the right thing and pony up for the LS7 versus the LS3 even though I know the LS3 will suffice. Now I wont worry about kicking myself and not getting what i wanted.
No boosting for me, straight up motor.......
thanks for all the input!
