Scott,
Dave's advice is, as usual, very good.
Post the following information and you'll get helpful replies.
1. Year of your truck.
2. Year of the 216 engine.
3. Year of the 235 engine (and, if came from a car or a truck).
4. Transmission/rear-end in your truck: is it original to the year of the truck; otherwise, give year/type information.
