Ok this is getting rediculas for me now.. i have some money saved up and i am changing ideas on what to do(Turbo) (Supercharge)(swap)more then i change my drawers. i found a good deal on a 6.0. Question is what is the difference in the 6.0's out of the express vans, it is the lq4 correct,the comp ratio is 9.4:1 where is the other differences in this motor at. is it the cam the tune..... Any info would be a big help..

 

The intake is different.

 

Yes, that would be the LQ4. Anything except the Escalade AWD, the SS, and the VHO, and the 05 newer 6l's is the LQ4. The connection rods, and pistons are the only differences. Cam and tune would be the same, and should be trashed anyway, they are way too tame

 

Whats different about it?? This is news to me.

 

ok this is a 05 engine i beleive so the intake is the only difference, I think the hp was 300 and tq around 340-60..

 

My bad, its 06 when they did away with the LQ4

 

I know the intake tube is different on the 05 and newer engines due to the electric fans, but I thought the intake manifold was the same.

 

ok can i get away with using the intake that is on the motor or will i have problems with hood clearence..sorry for all the ?.

 

From my intake manifold up is all my stock 5.3 stuff, except for a cheap ebay open element filter.

 

Manifold on mine was the same. Except for the EGR fitting beihnd the TB was eliminated.

Mangled,

Use the manifold, youll be fine. Its the same as whats on your truck now.
