someone asked for an elaboration of the injector comment,

How to choose injectors in 2019

In the past, say from 1995~ to 2002~ roughly. It was a very good idea to match the size of the injector to the exact power you expected to make for street cars, because it gave the best resolution in the fuel map for daily driving and economy features, and if you wanted something larger say 80lb/hr+ you were usually stuck using low impedance units with poor control for low speed operation. It punished you hard for choosing a huge injector if you didn't actually need one.

However, injectors are remarkably easier to control these days, and computer-microprocessors have become more reliable and much faster as well. Circuitry (injector drivers, amplifiers, techniques and basic ICU for controlling voltage signal) has improved.
What that means is you no longer need to suffer when using larger injectors.
You can now buy 1000CC, 1400CC, probably even 2000CC injectors that will run and drive fairly well in a daily driver application, especially when using high volume flow fuels like E85.

If that wasn't enough, there are two other benefits to using a much larger injector than needed for the application:
1. The injector driver will run cooler during max output, thus it will be more reliable, the injectors will be at a lower duty cycle using larger injectors.
2. larger injectors give more weight to injector timing curves, since more fuel is injected in the same amount of time, more fuel can be fit into a short window.

And lets not forget room to grow is on the table
