maby not, I'd imagine a engine rebuild would run 18-25k, so costly anyhow whatever it takes to get going then buy new or build ur own expedite truck starting with the cab and chassis
id rather buy cheap n rebuild,, other than spending 28-40k and possible do the same thing shortly after, or buy barley used or brand new down the line in the future when u have the reserves or capital to do so, anyhow
