It should but a 4.3 is a small engine for a 2500 van.

Double check the salvage yard interchange book also.

ended up not needing an engine. it was a blown intake gasket. cost me $560 at a local shop to get fixed, but my van is running better than ever again.

Thanks for posting back how it went and what it was.
