Well I have a question, In three weeks I am planning on doing an ls1 swap. I have a decent size cam and a nice set of ls1 241 heads but my question is will the stock injecters on my 02' 5.3 work?? Thanks in advance for the help, Brandon

 

unless you are going to make more serious mods to it, you should be just fine.

 

If you're swapping in the entire LS1 then your injectors wont work without modifying the harness and rails. If you're just using the short block and keeping your stock intake manifold then all will be fine but I think you're going to run out of injector.

 

yeah expecially if your goin to spray it..

 

if you are going to run N/A then you will be fine don't worry
we have just put 5.7 in with 4.8 injectors everything fine
