Hi, JIM GESSNER HERE. My website
www.vettefinderjim.com explains who I am. I am happy to help. Call me if you want between 8-5 PACIFIC time, 3 hours later from you.909-794-7905 is the number. You may have a correct dated engine in this car, but generally the cast date and assembly date, and head date are all about two to three weeks prior to the assembly date of the car. Same with the transmission and differential dates. Never say never however. That is why we have seen as much as 6 months variation and judging allows that.
