master cyclinder can it be moved
I had a '70 with a 440.
Part of the trick was to leave the top side low to its mounting surface & rotate the bottom edge up.
There was some wiggling involved & it took a while.
That was also over 30 years ago & I promised myself to never add another 440 to another A-body.
Just too much of a PITA for street driving & the related maintenance.
