These are OEM injectors from GM designed for the 8.1L [Vortec 8100] truck engines. I thought they were the same size as LS1 / LS6 injectors but they are shorter. They will work with truck intake manifolds, or the new LS2 intake manifold from the C6 / GTO. So if you're doing an LS2 intake conversion and don't want to put spacers on your fuel rails, these are the right injectors. These might work with your custom fuel rails, too. They will require tuning if you're changing from stock injectors, of course.



Racetronix has them for $45 apiece. I'll sell the whole set for $275.

 

If these are the marine injectors that flow 44 at 58psi I will give 275 shipped. Thanks
