GM 6.0 Liter motor question...

[JackdUp]

Anyone know the mechanical and performance differences between the GM LQ4-U 6.0 liter and the LQ9-N 6.0 liter motors?

im sure brian does

compression is higher on the lq9

[Quik]

LQ9 has flat top pistons which makes for 10.1 CR also has stronger internals

LQ4 has a dished piston which allows for 9.4 or 9.5 CR depending on the type of heads [iron/alum]

stock for stock LQ9 better NA motor but ppl do boost them
LQ4 is good building block for a boosted application with its lower CR

Thanks for the info everyone!
