Man, around where I live used TBI's are $100-$150, how on earth did you get one for $30.00?? Also, does it matter what vehicle you get the 4.3 TBI from? I did see one TBI for a lot less that was from a 1991 Astro with the 4.3 engine.

One more question- you reinstalled your old injectors, why not use the 4.3 injectors?
