My daughters 1998 Pontiac Grand Prix GT has a 3.8 engine, naturally aspirated, with various problems. The shop says it needs a new engine. The problem is a cracked head. The question is that my boss has offered me a 3.8 out of a 1995 Olds Sillouhette van. Will they interchange without much problem?

The 95 is probablt a series I and the 98 is probably a series II. Not interchangeable.
