I bought a 59Chevy C60 grain truck today. at first glance I thought it was a 348. Then closer 'inspection' makes think me 454. A repower. See telltale signs of a swap. My question,is when was the 454 introduced?The truck was last liscenced in 91. The woman(in her 80s) says she last drove it in the late '70s.It was 'her' truck.It also has power steering,15' rearhoist grain box,and a tag axle from(I think) an old IH KB5.Tires are decent.Stored in a barn since 91.Cab is straight as a pin,no rust. 1/4" dust on it,A mouse apartment complex. (YUK!!) Pd $250.00. A neighbor helped me drag it home.
