Is it just me or were a lot of Z28,s built in April? Just seems like I see a lot of 04 cars.
FWIW my Z/28 db [about 5% of the total] shows Z/28 production peaked in February and May at Norwood; January & February at Van Nuys.
Maybe people were getting "spring fever" and in the mood for driving a new hot car after a cold winter. Maybe.
Chevy stopped accepting Z/28 orders in November '68; dealers were ordering far more than they could build. When the dust settled, they were on allocation. Engine capacity increased shortly afterwards.
Probably most Z/28s were ordered for stock. Dealers didn't want to inventory slow-selling high-performance cars over the winter.
