Thank you for your input,
The truck I'm dealing with is 1992 Astro Van. My plan is to buy a new
350/350 for the Astro. At this moment my main concern is the setup for
the TBI, witch components I can recycle from the V6 4.3L engine & what I
have to buy additionally. 
Are you saing that the computers are identical V8 & V6?
Are you building your engine from scratch by some special recipe? Please
tell me more about your setup.
