W7 INFO
Both of my sets were blue plug.... it was just as the more educated I became about the W5, the more I could see subtle differences between the sets. My original set had a lot of porosity, even in the cnc ports. My second set looked a lot different, smoother finish. That top end i sold is on a built engine just waiting for the car to be completed.
Man this was such a great running mill. The car wasn’t legal for 9’s so my dad was shifting it around 5600 and running low 10s. On one of my visits to SoDak we got in the test lane towards the end of the day with a 6800 shift point and ran a 9.82. I think we could have gotten a 9.6 out of it with some tuning. After my dad hung up his helmet, I sold my Mirada after 27 years and kept the Duster. I had it caged and certified.
