What electronics are you going to use to control it?
Edit Deux: Is this the 302 you mentioned in your other post?
Yes, they are injectors.
Today I was looking at the MS3Pro. It looks rather friendly, but I'm undecided at the moment. I'm still working on getting all the mechanicals in order, verifying firing order by cam, mostly just seeing what I got! I kinda don't want to disassemble anything, but I'd love to see if the roller cam has any markings. I'm short some push rods and need to plumb the rockers through the head. I also need to plumb the remote filter. I need to make sure that everything that is supposed to get oil, does. Kinda reverse engineer what's been done to this thing.
You know, the never ending "to do" list.
This is the 302 that I was figuring out what I needed for a bellhousing in my other post. I might have that part a little figured out. Still working on it.
The MS3Pro appears to have a good set of features on paper, but I have never been impressed with any of the megasquirt products I have used.
Have you looked at the Haltech units? Depending on what features you want, it might be a better option for you.
Do you know what you want to do for ignition? The Haltech supports drive-by-wire where the MS3Pro doesn't, but with what you have there going cable throttle probably makes more sense.
The Haltech can control a 4L60e and a few other transmissions if you decide on a modern automatic. The Haltech also supports closed loop automatic tuning. Whether that is a bonus or not depends on you.
I saw your post in the youtube thread about sensors, but it seems more applicable to this thread so I will comment here.
You asked about measuring airflow on this engine. You would really need some kind of MAF per cylinder to do that. I will see if I can find a small one that would fit, but it would take some custom work.
I suspect that you are going to have to run this in speed density mode though. Not knowing the cam specs will make tuning that harder, but it is doable.
Depending on the ECU you go with, you will probably need MAP (manifold air pressure) and IAT (intake air temperature) sensors.
