Step 1 Add Video

These videos are detailed information on how to do a truck swap on your LS4. No where will you find such detailed instructions!!


Step 1:


Go to your

Junkyard. Find

any vehicle with

the Lq4 intake:

Engine info: 4.8L, 5.3L, 6.0L

Vehicles: Chevrolet Express/GMC Savana

Chevrolet Silverado 2500 Pickup, 3500 Pickup, Crew Cab, and Chassis Cab/GMC Sierra 2500 HD Pickup

and Crew Cab, C3, Denali, and 3500 Pickup and Chassis Cab, 1500HD Crew Cab

Chevrolet Suburban/GMC Yukon XL Denali

Hummer H2

GMC Yukon Denali

Price: should be around $25-30



Brake Booster-Billet


If you are planning to install truck throttle body, here is the part number and etc:

ACDelco 12679525 GM Original Fuel Injection Throttle Body with Throttle Actuator


Re-applying this fitting is specifically for a LQ4

Truck throttle body install, and can be used for

your LS4 EVAP system. If you are going

with a LS2/3/7 throttle body, this fitting will

need to either be

plugged/deleted, via plastic welding to close,

or capping; and certainly tuned out! IF you

plan to keep your LS4 Throttle body (adapter

plate will be needed!!), you will be

able to keep your evap system online, but you

will still cap, or delete this fitting on the intake.
