The 302 EEC won't be tuned correctly for the 460. There was a thread here somewhere about that. If it were me, I would get a MAF EEC from the 5.0HO and get a tweecer. That would allow you to make the changes necessary.

the 96 computer is not any better. run the 5.0 eec a9l ecu and have it chipped. you can use a 460 efi dizzy. and stay away form the tweeker. i have seen a few guys trying to get there stuff tuned with it, but it just was not doing the job. just have the thing dyno tuned and chip the a9l...you can also use the a9s

if you cant learn how to tune it yourself then yea get it dyno tuned and they will A. chip it OR B. tune it with a tweecer, QH or somethign like that maybe even want you to buy it. and it will probably take multiple trips to the dyno because they can't tune for every load and every temp and every cold start condition ect, ect, ect. if you want to go this route GO TALK TO THE SHOP THAT WILL BE DOING THE TUNE. ask them what THEY like to tune with.

or you could go stand alone and throw the MAF in the trash (what im doing)

I have a tweecer on a supercharged 302. You could do 460 with a tweecer, but it would requirer a lot of story telling, and fake numbers to get you to the goal you want. You can turn most all of the functions off. You can break it down to just dictating fuel in an open loop, and dictate timing. You may find it to be to much control over what goes on. Most have a hugh learning curve with it.

I would think it would be easier to use a stand alone. The ones I have seen used are easier to tune than my tweecer.

A chip would be a good option if you had someone around that could do it. There would just be no changing it for tune after you get it. That can be good or bad.

Tweecer is a piggyback unit that plugs into the EEC and allows you to override most of the settings.

I looked into the megasquirt, but I got an amazing deal on an AEM EMS. SO I'm going that route.
