Most older diesel powered buses/coaches had 2-stroke Detroit Diesels, Like the 6V-71 & 8V-71.

A 6.5L TD isnt a upgrade to ANY diesel....Except maybe a 5.7L diesel or a broke 6.5L, & will NOT be a direct swap!

The most "straight forward" diesel swap would be a Detroit 6V-71....There is most likely a identical but Detroit Diesel powered chassis out there...But a Black smoke blowing, Underpowered, Loud, Oil leaking dog is what you will get.

The Green Leaker. Most efficient way to take perfectly good diesel and turn it into nothing but smoke and noise.
