I have won a 1971 Z28 RS blue with black stripes in Cali. Located in Pasadena and Walnut Ca.The seller works at UCLA and also has a 1966 Chevelle SS Looks good in pics but owner is avoiding engine casting number details. He says rebuilt LT1 with original block heads,intake and carb. Decked block so 3 letter code is missing. Build sheet says 330 hp. fairly convinced real z28 BUT not yet convinced about the motor. Anyone know the car?? The seller might post here too but I don,t know his user name if he does.
