Okay I'm putting a lq4 into my 2000 camaro ss and I'm using the ls3 intake i know i need the injector adapters, map adapter, and the cable bracket. But do i need i to hook up the fuel lines because the ls1 fuel rail has 2 hook ups but the ls3 only has 1? Also if i put stock bearing back in the rods and crank can i just throw the new ones in and go or do i have to check the clearances and stuff like that?

 

Anyone???

 

Are you using rectangular port heads? The ls3 engine has rectangular port heads. Your lq4 does not. So, unless youve done a head change-out, the intake wont work. The ls3 engine also uses a returnless fuel line system. Your camaro used a return style fuel system, meaning the fuel that wasn't "needed" at the injectors, was returned back to the tank at part throttle operation. It's always a good idea to check clearances when installing new bearings. Most guys wouldn't bother. Will it work? Yeah.

 

yes i will be using ls3 heads also i should have put that in there. Okay so do i just block off the return line then?
