You'll be getting into a lot. The key character trait you need to keep is PATIENCE! It doesn't happen overnight unless you have deep pockets. Take your time, unless you're in a hurry. My swap took at least six months. Some have taken a lot longer than that.

RedHeartBeat can probably shed some light on your swap more than me. I think the 88s are similar to the early 90s trucks (don't quote me tho). If you're just looking for ideas, just skim over the thread titles in this forum (LS1 Conversions). You'll see a few "swap" threads to see what others have gone through. The material's there, just need to look in the right places.

Others are glad to help (when time permits to log into the forum).
