Although the Boss is a radical engine, just can't put one between my Cobra's frame rails. Mustang etc, yes....
Would still need an intake and carb.
An FE would be the easiest. I have brand new parts,...steel bellhousing, billet flywheel, dual disk clutch and motor mounts.
On my first 428 FE, I used the Edelbrock RPM manifold, on the rebuild, I went with the taller airgap and I had to mill down the car surface a bit, so it wouldn't touch the hood. There was no loss of power.
I don't know for sure if the 460 would fit under the hood. I know theres quite of 460's in Cobra's, but some have a taller hood scoop than mine.
I have my Cobra pretty low, so if I made new motor mounts the pan may be too,....low. I need to measure ans see.
For some reason, (maybe because I'm a power freak)
I can't get past the power, especially torque down low, of the 460. The low RPM T/Q
is amazing.
This is just from one noted builder,.....as example only. Was easy and able to post dyno graph.
