i have a chance to buy some 42# injectors that are out of a ford lighting. my question is will they work in a lt1. they are ford motorsport injectors, i dont know if they are simalar to svo or not. oh and they have a green top.

 

I dont see why not. People run ford motorsport injectors all the time. Same design. Just keep in mind that they're flowed at a lower fuel pressure so at GM fuel pressures they'll actually flow like 1.5-2# more than the rating.
