Factory eco injection.

I dunno, Rusty- the magnum intake has different bolt angles, and the shape of the "kegger" intake kinda eliminates the possibility of redrilling them at the LA angle. No provision to mount the crank position sensor on the LA, either. Not insurmountable, but...
The '88-'92 factory TBI setups would fit, but they're not tuneable and some of the parts are going NS1.
I have thought about this a few times. Just add injector bungs to any cheap LA intake. I bought a set of injector bungs but don’t have time yet. ICT Billet 551313 ICT Billet Fuel Injector Bungs | Summit Racing

I think there is a Chinese single plane available in Australia that is not offered here in the US, so no idea what it costs.
There is an Edelbrock Super Victor EFI that is LA pattern with big injector bosses and holes drilled.

Even on a Magnum, making power with factory EFI gets sketchy because no SFI flex plate is available. So how just making a smaller size, more typical style front mount tone ring and mounting a crank sensor up front. I have not tried it yet but it’s on my mind.
