Back in the day, there were a lot of small block Chevy motors in previously six cylinder Broncos. That motor actually fit better than the small block Ford.
You know that notch in the Bronco firewall? it was made to accommodate the longer six cylinder engine, but fit Chevy's rear distributor perfectly.
Also, The small block Ford has a front oil pump that had to be adapted so it could have a proper rear sump for 4WD use. Chevy motors already had that feature.
Personally, I can't think of a more appropriate motor in a Bronco than a GM LS type motor. Lots less mods are needed for an LS than a Coyote.
We routinely use Caddy brakes, Jeep trannys, and various diesel engines in our Broncos but somehow swapping gasoline engine manufacturers is taboo.
This is a crazy world!?:?

yeah but who is the actual manufacture of the parts;)

If someone made a LS-to-C4 bellhousing, flexplate starter set up specifically for us black sheep.

Does the LS even require a new serp set up?

They do make it;D fly wheel is too and the starter that comes with the motor works just fine

LS's only come serpentine and in my experience fit just fine.
