|Re: crown bus engine upgrade? by Phil Feinstein|
|If you take a look at http://www.angelfire.com/biz/snwvlly/busses/repwr.htm, you'll see the replacement of a 4-71 Detroit Deisel with a 391 Ford V8.
There's no doubt in my mind that it can be done and that you'll get more power and efficiancy with a newer style of deisel motor. There are a few considerations.
* What is the absolute size of the engine bay?
* What is the length/width/height of the engine that you want to swap in?
* Does the transmission attach in a manner you can live with?
Obviously, if the motor is bigger than the engine bay you can't use it. As a rule of thumb, you shouldn't use an engine that exceeds 90% of any dimension in the engine bay just for ease of service. If you look at the 4-71 to 391 conversion, you'll see that he had to craft motor mounts and lucked out because he had a heavy duty trans that could be grafted to the transaxle via a driveshaft. The roadrunner was a pretty common tranny at one time, so you may find that it will bolt up to a newre engine or that a bellhousing is available to connect to the newer engine.
DO YOUR RESEARCH. Nothing kills a project like depending on a part that doesn't exist.
Hope that helps!
