Well guys. The week is soon approaching. I won some 5.3l Ported heads with oversized valves, .650 lift springs. Im adding a large cam and headers as well. Now for the fuel injectors...What size are stock and what will I need? I don't want to break the piggy bank. Any gm vehicles like maybe ls2? That come with larger injectors? I don't want to have to buy some name brand injectors that will kill my pocket book.

 

Your car comes with 28#.

You'll need some SVO 30s for your car, which act like 36#ers under LS1 fuel pressure.
