Would there be interest in a dodge TBI setup made for our cars?

Let me be a little more specific: as TBI systems go, the Holley ProJection system was junk. The GM system was markedly better. And if you really don't understand why people are even interested, then you probably have the luxury of enough spare time and money that you don't have to understand. I agree with what seems to be your philosophical standpoint, that a job worth doing is worth doing right. But a junkyard TBI swap is vastly easier, faster, and cheaper than any kind of port fuel injection retrofit, and while the end result isn't as good as port fuel injection, it's still enough better than a carburetor to be a very cost-effective option to consider for those unable or unwilling to spare the time and money to do a port fuel injection swap.

Now do you understand why people are interested?

Yes and no. Most yards down here will not let you pilfer around. So that means trying to find one that will and then trying to find TBI stuff that actually might be useable.....and not crushed. And about the money and time thing..........LMAO. I simply have always been good at building and tuning carburetors and carbureted fuel systems, so that's never been an issue for me. Remember too, that where I live (central Georgia) is not the coldest of climates and we general don't have to have immediate cold weather driveability. ;)
