I wonder what yr that guys 6.0 is? i can verify that it isnt. Like below is a 04 and the only availible transmissions were a 60/65e.
i want this set of heads sooo bad im like flipping out! They flow over 360! (they told me more like 375!!) , 245 advertized intake cc(but really more like 255) and for 500 extra this guy promised me 15 cfm more with some hand porting.

MANNNNNNNNNNNN I was thinking about buying a vette but i dont know,i may just take the little money i have and buy these..

If it's a 4L60E, I won't need to swing by Saturday to look at it. I already have one of those!


Thanks!!!
Anyways about it the only difference between lq4 and lq9 is a lq4 has a 5cc dish piston. Not much of a difference really.
Now the 04+ lq series engines has updated rods which has been proven to hold well above 750whp. Yet the earlier rods where around 550whp. Also some of the early 6.0s had a different crank, the area where the flywheel/flexplate bolt on was deeper then others.
