Do you have access to a programming guru? If you stick with stock programming, your parts choices are quite limited.

Budget?

Staying SD without any sort of tuning is going to severely limit you.

Gt40 heads, stock cam and 1.7rrs and explorer/cobra intake with 65mm Tb might be the limit of what you can do without tuning

No, the A9L is not the only option although it's probably the most common. No, you would not need to rewire the whole car for Mass air. There are a few pins at the ECU that need changed as well as the Mass air connector that needs added. You can get the Mass air conversion harness from LMR, it comes with the instructions on how to change your speed density car to Mass air.

As far as the Tweecer goes, I can't answer anything about it but I'm sure someone can.

Vs convert to Mass Air?

Are you planning an aluminum headed 331 with a turbo? Or a basic Gt40 headed combo? If the later, save yourself some headache and just swap to mass air.

I did it to my ‘88. It’s 7 wires and about 1-2hrs of work.

You need to be a wizard to understand the User Interface. Tuner Studio for Megasquirt is much more user friendly.
No MAF required, no rewiring of factory harness.

I converted my ‘86 5.0 to mass air years ago. The process is pretty simple, but you have to move several wires to new positions in the ECU connector. There’s a tool to remove the connector pins. I’d do the conversion first thing.
