my question is will a ls1 intake off of a 1999 z28 camaro fit on a gen III 4.8 engine that is in a 03 silverado? they are basically the same style engine, i have heard it will fit but i wuld like to see if anybody on here has ever done it..thanks guys!

yes they fit but you need to use the car accessories unless you can rig something upto work, they mount different on the cars and trucks and i believes its the trucks they use a hole in the manifold as a mount.

they do work, but work is needed for em to.

make sure its from an 00 or up, so its the LS6 that came factory on all ls1's, if its before that, its a waste of money imo.

yea the intake i bought came with the injectors and fuel rail for the ls1..witch the plugups for my stock 4.8 injectors are different from the ls1 injectors so i guess i needa cut the injectors wires off of a ls1 motor and wire them to my wireing harness?

the 6.0 truck intake makes more power , but i guess for clearance ls1 is shorter
