It was the time to own a Van ... So I got one ... 1977 Chevy "Of Course"... Had an old 307 core laying around  ( So many people Under Estimated a 307 for some odd reason )  We put that engine in, And off we went, Up the Tenn. Mountains  No Problem ... Even pulled a 24 foot trailer to and from Orlando on occasion .. 307, 342 gears .. No Problem !  And what  a sound system, Received a case of oil filter's and 5 cases of oil from Chevy for this one !!!
