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.

It is just about 20" from crank center to top of Truck intake.

depending on what it's in, with my 70 tempest the part that hit the hood was front TB area on the truck intake, I cut of cut off the inner support where it hit the hood but, decided to go with the LS1 intake.

Thanks, I was getting around 20" based on searches, but got conflicting numbers from different sources.
91parkave, I'm guessing you needed to change injectors, rails, computer, etc to go to the LS1 manifold?

Keep in mind that if the hood slants forward at all the part that will be more likely to cause interference is the alternator.

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.

I didn't know it was that easy.
How about theTB spacer, did you make that or is it available? Goy a pic of the final installation?
