      Yeah – there’s a “lot” of on-road 6bt’s of various vintages from dodge’s and step vans, to medium duty trucks and school busses.

      The 4bt on the other hand really on came in step-vans and other oddball applications for on-road engines.

      There’s a bit of a supply-and-demand thing going on there

      I really have a difficult time believing that. Around here 6BT is the big ticket item. I think it’s more reliant on location.

    I am going to buy a step van cargo truck soon, like the ones Fed Ex, UPS uses for residential deliveries or similar. Would it make sense to try to find my truck at a junk yard without the engine and have the 4BT installed. I am sold on this engine due to it’s longevity, mileage, and reliability.

    Hello, im a diesel mechanic in alberta canada. Ive got a 4200 service truck with a vt365 pos. With an allison.
    How hard would it be to put in a 6.7?
    Would it bolt up to the allison?
    Id like the reliability and a bit more hp.
    Thanks for your input!
