could... i'd keep the electronic hardware frm your original engine intact and able to transfer incase of technical changes.

i had a dealer put in a refurbished block in an 89 riviera.. the dealer shop actually put in a older block in and transferred my electronic hardware into it. should've done the job myself but was time pressed / working. the the original block in my case would have been fine to keepp. 3.8 is quite a tough engine.
