Injector choice for 4bbl conversion

I am wondering if anyone knows a good donor vehicle for an injector assembly that will physically bolt to a 4bbl carb manifold. Just trying to get my ducks in a row. Could I use the sensors from the same application, (ECT, IAT)? As I understand it I don't need a MAP because it's integral to the MS module. True? Thanks a million for the help.

The GM TBI units are not a direct bolt on, but there are off the shelf adapters that work great for them. See one in action on our Nova.

Yes - although for some perverse reason, many GM TBI cars didn't have an IAT sensor. The ECU has to guess it from coolant temperature. Bean counters strike again!

True.

Matt,
Outstandinf info! It looks so easy. I may just give it a shot after I get my tax refund :) Thanks again
