3.9 Stroker

Unless it's a Shelby Dak, V-8's are not a drop-in at all until they switched to the body like the red one above, that's why they changed the nose.
What are you talking about? I have done V8 swaps in a 1993, a 1995 and the latest is a 1997. I put a 5.9 in the 1997 and it running on a 5.2 PCM. Hell I even used the V6 wiring harness on it just added the wiring for the #7 and #8 injectors. Same V6 transmission, convertor, even the motor mounts are the same. It's the easiest engine swap ever.
