The rear lower mounts line up, the rear uppers & mid lowers need new plates & from memory (it was nearly 40 years ago) the fronts need a bit of fiddling. You may also need to take the cam cover off to get the motor in/out but again, my 1000 then 1100 motors went into my '78 750 a long time ago.You do not have permission to view this gallery.

I have a 77 GS750 (actually Aug '76) and it has a 78 GS1000 engine installed. NO - it doesn't just slide in LOL... I have all new info and pics if you are seriously thinking about this.
Lower rear mounts line up perfectly
Front right mount works. Front left mount needs help - I welded up a 1000 and 750 mount
All other mounts need help - lower center left mount on mine isn't installed.
Easier to install without the valve cover and if adjusting the valves - I remove the carbs to make removing the valve cover easier.
No other "real" issues except for - are you ready for this - the right foot peg hits the case and needs modified. I've got a work around right now but looking into ALL options.
Yes, this is a real GS710 and it runs very, very well.

I have a gsx1100 engine in my 77 750 and you have to make some new motor mounts but thats pretty much it. As far as the valve cover as long as I remove the breather cover first I can remove the valve cover with enough clearance. This also goes for engine installation and removal. Maybe I also removed the sump pan.
I use rearsets on mine so didnt have to deal with engine interference
