the only difference between a lq4 and lq9 is some compression and about 30hp... most of that can be accounted for with a tune because one compressions point alone is good for 4hp IIRC, it's what you do with the higher compression is where one shines over the other. IE, higher octane fuel enables you to advance the timing more and timing is power. either engine will get you well over 400hp with the right mods and tune.

Mine is a 2500 pound paper weight right now but I have a th400 and 3.8:1 atlas with 4.88's and 37's. when it moves on it's own I'm pretty sure I have the gearing nailed for the power. I do plan to swap in a 4l60,65 or 70 in place of the 400 and at that time I'll probably do a 4 speed atlas at the same time for no real reason other than I want more gears.
