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

Right. Only about 150-200 bucks parts AND labor. If somebody's not ready to dump that small of an amount at it, they should stay with a carburetor.

I never looked into the cost of individual injector's. $150 sounds pretty cheap for performance oriented injector's. Is that a used price from an autowrecker's? In example;let's say I decide to do this for my 451. Now how expensive is it? I need an inj that will keep up to at least 650 h.p.

Before you jump on this,I was never going to install tbi on the 451 unless I could get performance out of it. The tbi was more for the 400.
