i don't know enough to answer that. but all i needed, originally, was a useable 3.4l block for the rebuild. they, jagworks, responded that they had one and it went from there...slowly.

 

I’ve seen good reviews for Blue Prism Automotive when it comes to used and rebuilt engines. They specialize in quality-tested replacements, so you’re not gambling on an unknown history. Worth giving them a call to see what they have in stock!

 

I just listed a seized 3.8 in the market place for $500

if you cant find what you need, this could be your new building block.
