had a 38 chev coupe stock except for a split manifold and stars on de mud flaps.
and i thinkzzz de speed limit way back then was 45-50 it cruzed real nice at 50 most all day runnin all over az and so.cal.
but a pickum truck is most likely lower geared so maybe your lookin at 45-50 tops.
but the lower speed limit on most interstates is 45 mph just smile and wave at de nice folks that fly bye
