'70 Dart 392 Project; what direction?

Are you planning to lock it in long runner mode or short runner mode? The linked one locks it in long runner mode.

Honestly, seems like if someone were to lock it in long runner mode, why not just get a 5.7 intake and call it good. Ports are the same at the head, I bet there isn't much difference if the 6.4 intake is set to long runner mode. And a 5.7 intake is a ton cheaper than a 6.4 one.

But I'm just speculating.

You bring up a good point and I hadn't thought about the 5.7 intake. I already have a 6.4 SRT8 intake sitting here complete with fuel rails and injectors so I'll still use it. Previous owner said it had the big factory injectors, he swapped it onto a 5.7 Charger RT and was overfueling drastically. It's better to dial a big injector down then it is to overrun a small flow injector so don't anticipate any issues running megasquirt.

I was anticipating the "long runner" mode just to help with low end but I don't think this engine will be suffering from lack of power anywhere. If I don't do the delete plate, do you know what it defaults too?
