Man those things are expensive. Love to have one if I could swing it. All the cost is wraped up in the throttle body and the injectors. I looked at this stuff alot and there is a good forum on the megasquirt web page on building your own system for way way less if you know how to shop. Car Craft put the megasquirt system on a 350 and gave advice on how to do it cheaper then they did. They mentioned certain throtle bodies that you could take of some trucks and using the quad 4 injectors and having them rebuilt. I wonder if the Edelbrock system is a batch fire and if it controls the spark or not. I wish someone would make a tune port type manifold for them.
