FWIW I run 850cc injectors on 2.0 liter 4 cylinder and it behaves just like stated below. Idles around 12:1 or a touch richer, but idles good. I smoothed the VE table around idle and I don't seem to have a problem with it so far, but definitely tougher to work with than smaller injectors would be ...

I don't remember for sure, I would have to measure it. I remeber talking with the guys down there and they basically had this one that was bored out larger as an experiment and setting on the shelf, so I took it.

I had the TB bored out to 1000cfm. The manifold has port injector bosses, but they won't be used. The supercharger comes with either single or dual top plate according to the manual.

Here is a pic for you of the setup so far

That is good news. You have almost the identical setup I have. I am going to run a B&M 250 on top the 454. I was going to go with a set of 150# injectors and run them at a lower pressure, but I may use a smaller set at 35psi like you are doing. It will be interesting to see how the supercharger ...

I should also clarify that I will be using port injectors in the throttle body. And specifically the auto nomics TB which has an angled injector placement above the throttle plate.

Are you having any issues with the injector spray above the throttle plate. I am getting ready to order injectors for mine and I need to decide if I want to run a more normal EFI fuel pressure like 35psi or lower like 15psi. How has your experience been?
