changing from TBI to Carb?
 

I have an 89 W250 with a 318 that has the TBI on it. I got an extra motor with the truck when I bought it. Its another 318 out of a 92 conversion van. I am wanting to take this motor and do a mild build on it (small 4 barrel, new intake, cam, and hearders).

My main question is what else do I need to do to make the change from TBI to a carb.
