Okay lsx gurus...
I am swapping out my injectors for some ls3 length injectors...
first thought is to get some SD 60lb'ers to replace the ls1 length SD 60s I took out. These would be direct replacement nothing new. They seemed to work fine, but idle and cruise AFR was hard to get to stay steady, did bounce a bit within a few tenths.
2nd thought is LS3/7 stock injectors, but at 42lbs (@3bar), I am not sure it will be enough for my 416 (expecting 550whp range), I really dont want to go above 90% duty cycle
3rd option is LS9 injectors which are 52lb, but the spray pattern is off and could hit the runner/wall, since the manifold sits at a different angle, though i have heard people have used these w/o issue.
4th option is FAST injectors.... though unfamiliar with these and how they perform, but can get 50 lb @4bar or 65lb @4bar...
Anyone have input/experience to share?
