To me, the problem seems to be related to the exp calculation
You are right. The accuracy of this function varies on different calculators. You should adjust the last term (40.1). For instance, on the 42/48/49/50G it should be 41.524, or 10*SQRT(569/33), if you prefer it so.
Of course, for the full twelve reversed digits on these calculators, another expression has yet to be found.

Is your message having been posted exactly at 3:14 a.m. a coincidence? :)

On the HP71B (with Math ROM) and HP50G:
GAMMA(COSH(10/3)+7347/7348)318/5 => 95356295141.3
On the HP32SII:
10 ENTER 3 / COSH 7348 1/x  x! 63.6  => 95356295141.3
