Why can you only go to 775?? where are you intending to run the bike and what class??.

Yes 1127 crank will go into 1052 cases, if I remember you have to open the cases a little to get the 1127 cylinder to go on. the last engine I did I used a set of T pot cases all black and brand new old stock with 1127 crank 1216 pistons six speed gearbox .

That's not a slabby tap.

The gearbox output shaft and swingarm pin does not appear to be on a level plane ?. will this not cause problems.

Andy Mcphearsons bike did go really well but recently had head done by well known specialist , just as head work can give it more power it can also take it away id start there if I was you.

What happened to the hindle pipe?.

Michael Dunlop's mega expensive oil cooled XR69 goes through the Sulby speed trap at 171 ish mph and that bike would want for nothing.
