Buy it. Maybe it is a 302......dare I say Z28.
Do not believe everything so called experts tell you. I have an all original x33 d80 car. That is Z28 with RS.
Cowl hood hideaways antenna in the back and all the trim upgrades. Additionally it carries both sets of emblems Z28/RS.
So many people don't believe mine is/was "possible" either. That is of course until they see it in the storage along with the GM documentation
