Hi guys thought of putting this on 2day, was looking at my vx ss intake manifold to see if it had a ls6 intake manifold and thought to look at the injector numbers and did some research and found out that it does have the ls6 intake fitted it has the ls6 injectors 12561462. So i thought this may help anyone the injector numbers are as follows- VT11 ls1- 12456154, 12555894 are rated at 26.2lb/hr @58psi and the VX LS6- 12533952, 12482704, 12561462 are rated at 28.6lb/hr @58psi hope this helps cheers
