They dont have to be a front steer .I know this for a fact. We bought three of these engines from Chip Ganassi. We put one in a Duster. We had a chassis shop relocate the factory steering box rearward a bit and he re-fabbed the drag-link and whatnot to make it work, but it does not have a rack and pinion. It has the factory steering box and it all cleared fine,although, it may possibly be cheaper to put a rack and pinion in.
These are neat engines and we make adapters where I work as well. We have even sold one to a Moparts member !
