I emailed summit racing about their EFI LS1 intake manifolds made by edelbrock. I wanted to see if any of the edelbrock EFI kits would fit on this intake manifold. They dont but this is the response I got...
"Our Pro-Tuner EFI, available later this year or early next year, will work with our EFI manifolds."
This could make the swaps easier and possibly cheaper in some instances. Deffinately something I am going to keep an eye on. I emailed back with a few more questions. I will post any more info I find.
I have seen the LS1 Victor Jr. Intake manifolds with a carb make some pretty sick power! Put EFI on that and it should be kick@$$!
