Pretty sure this one has the GM 327 V8 engine. I'm thinking of getting a newer style bus such as s 1996 international. That has an automatic transmission, air brakes, and a Diesel engine and swapping it to the old bus. You can pick up old buses such as this anywhere from $1500 to $3500 running and driving. Then restore the outside of the bus as original. Then, reuse some of the original seats inside and customize the rest of the interior. What do you all think?
