What's the Differences? I am looking at putting a 6.0 in my 68 Nova. I know the insides are different but what exactly. Between the Vette 6.0 and the truck 6.0. I have 10K to spend on my car and I found a few truck 6's for 3k and the vettes are 7k any advice and guidance would be outstanding. Great site. Glad I was told about it.

The biggie is the truck 6.0 (LQ4/LQ9) is iron block/aluminum heads, the vette 6.0 (LS2) is all aluminum.
The heads are similar in design, but have different chamber sizes (72cc truck/65cc vette)
Cams are different (vette has more duration and lift)
Intakes are different
Sensor locations are different
Also know that there are two versions of the truck 6.0 which are externally identical
LQ4 - 9.5:1 compression due to dished pistons - rated at 300 hp/360 tq
LQ9 - 10.08:1 compression flat top pistons, thicker connecting rods - rated at 345 hp/380 tq
LQ4s are sold in HD trucks and GMC Denalis. LQ4s prior to the 2001 model year had iron heads, and have a longer crank that will only bolt to a 4L80E. These engines can typically be found cheaper than other 6.0s because to the heads and crank. In 2001 they received aluminum heads and a common crank with the rest of the Gen III engines that will bolt up to a 4L60E.
LQ9s are sold in all versions of the Cadillac Esclade, Silverado SS trucks, and Chevy and GMC VHO and Vortec Max trucks.
