I acquired a 1969 dated ZL1 from an aluminum fabrication shop in New York. The person that owned the shop had a ZL1 motor that he used as a jig for worrking on heads of all things. After trying to buy the motor for 5 or 6 years he finally let loose of it as he was losing his lease on the building . He told me Billy/ Wonder was the person he got it from and that it was used at one time in the wonder wagon. In doing some internet searching there seems to be alot of different wonder bread sponsered cars,and a few vega wagons. Does anyone know any history about these and specifically ZL1 related cars that were sponsored by wonder bread???
