I jus did an L92 swap on my 07 Avalanche. I was wondering if I should keep the l92 injectors on it or put the 5.3L flex fuel injectors my original motor had..wut do you guys think?

 

Don't know what the L92's flow, but the FF's are rated at 33lbs. IIRC.

 

Stock L92 injectors are 31lb. If you want a cheap upgrade source out some LS3 injectors they are 41lb and you can usually find hem with intake and fuel rail for under 300 bones

 

to run LS3 injectors you need the FAST height adapters for the injectors, they are a 1/2" shorter than the truck injectors.

keep what you have the times/cam in my set up spin 6800rpm all the time and im 104% cycle duty on my L92 injectors. thats at WOT after 6300rpm

 

5.3 flex fuel


6.2
