LS1 intake on a 5.3 engine
LS1 intake on a 5.3 engine I need height clearance so the vortec manifold has to go, will the stock fuel rails and injectors from a 5.3 engine work on a LS1 intake manifold without much mods. Will the computers work with the LS1 intake on the 5.3 engine without splicing or tuning?

What are you putting the 5.3 into?
So the question remains, will the LS1 manifold mate up to the cable TB, the injectors, fuel rails and electronics of the 5.3?

yeah the intake will work but look at the injector plugs they might be different. the plug on the 5.3l wiring is smaller than on the ls1. the injectors on the 5.3l intake are bout half to one inch shorter than on the ls1. the computer and wiring will run it with the ls1 intake as long as u get every thing plugged in. if u plan on driving the vehicle i would go with a ls6 intake
No, the 5.3 fuel rails and injectors will not work on the LS1/6 intakes. The intake will work on the 5.3, but you have to use the fuel rail and injectors that match. The wire harness and PCM will work you just need to swap the injector plugs and tune for the injector size.

I put an LS1 intake on an LQ9 with 317 heads. I think the L33 injectors are the same.
The TB will bolt up.
The LQ fuel rails and injectors will work with minor mods. See this link.

I got the intake with rails and injectors, so I changed my injector pigtails and swapped everything.
