Crazy Question
I got a wild hair here and wanted to get some info and advise. I'm very comfortable working with GM's LS-based motors, but fairly new to Mustangs. I've got a request for some information. How difficult would it be to swap a LS-based motor into an S197? What kind of k-member clearances would need to be done? Tubular? I'm basically looking for any kind of info that would be helpful. Does anyone have any pics of the 4.6 motor out of the engine bay and of an empty engine bay? I'd need physical dimensions of the 2 motors to know if it would physically fit first.
Why you ask? The wow factor would be priceless. 6.0 Mustang has a nice ring to it. Also, roughly 2 grand for 1.4L of more displacement with an aftermarket that rivals the 4.6.
Any help would be appreciated. It's just an idea at this point but might develop into reality if some details get worked out.

external dimensionally speaking, the 4.6L is a big motor. If memory serves me correct, the LS based engines are actually smaller in external dimension. It's the big heads on the modular motors.
outside of that I'm really no help. I'm no certain the LS motor will bolt up to a 3650 5 spd without an adapter plate. So you've got to think about that as well. You may be changing the entire orientation of the drivetrain by doing a swap like this. You're looking at the possibility of having to modify the k-member, transmission cross-member, custom length drive shaft.
By the time you add up all those additional incurred costs to do it, you might as well build the 4.6.
It's not like the engine is some fountain of technology that only a handful of people know about. It's still an internal combustion engine, they all work the same. The only main differences is you have multiple cams that are on top of the heads instead of in the block.

Just go get a Camaro already.

We just put a GM transmission into the stang....2 speed powerglide. Had to fashion custom brackets, driveshaft etc etc.

If you want to work on a gm ls based engine, get a gm car with an ls based engine in it. Much easier fix if you ask me.
Swapping a ls engine into a mustang not only is just plain wrong, but a hell of a lot more work than just learning about and working with the 4.6 mod motor would be.

I think it would be cheaper to buy a GT500 engine on the FRPP's website and install it. (That I would love to see (as long at the rest of the car appeared to be a regular GT Mustang).....Is 5.4 litres supercharged good enough???
