I'm planning an LQ4/6.0 truck motor. Can anyone provide the height of the truck intake manifold? I want to see if it will fit under a stock hood.
Either the height from crank centerline or just how much higher it is than the LS1 intake.

No i decided to get the ls1 fuel rails to and hack the mounts down, so they would work with the truck injectors, i also used a aftermarket FPR at the rails via the fuel pressure service port. So no i didnt have to change the computer, injectors... harness...anything. Im using a TB spacer for the Truck TB to clear the water pump neck.

Have you got a pic? I think I'm going to buy a complete LQ4 setup and hope it fits.
BTW, anyone know what year LQ4s are drive by wire?

I cant be sure but they have been used since 01' my 01 5.3 has drive by wire, heres a pic of the camaro fuel rails, what i did was compare the bosch injector height to the delphi injector height and modified the mounting tabs accordingly, mine came out .63in shorter so i marked the tabs and sectioned them accordingly.
