Maybe a tech article?

I covered this setup once already including part numbers. But here is the gist of it:
4 bbl intake manifold
4 bbl to tbi adapter
4.3 throttle body with stock injectors
747 ECM with stock harness (or painless harness if you have the money) and sensors
Use acomputer controlled distributor from a late model 250 6 cylinder, part number available in the archives
Good luck on the appropriate knock sensor, I used the one from the 4.3, worked ok
The big cost is the 4 bbl intake manifold.
Stock chip from an 87 5 speed 4.3 liter astrovan worked best for me.
Looks like a 250 would be an easier swap!
