The 1984-1986 NCRS TIG states the 1986 heads were cast iron until mid production. What is considered mid production based on the VIN #?? How can I calculate the build date on an 86 based on VIN?? The last 5 #s are 26773, so would this be a cast iron or aluminum head car? Build date?
I have heard the CI heads were better, any thoughts?
Thanks, John.
