With the SR-71, I mostly climb with the autopilot. Granted, I
usually set at the default 1,100 fpm climb rate, but I didn't think
that would be too much of a problem for the fastest (known) plane in
the world, a plane that pulls Mach 3.3 at 80,000 feet. At some point
well before 80,000 feet, the autopilot more or less fails, pulling the
nose up into a stall.

Checck WWW for somew real-life SR-71 procedures.

Get her supersonic at 30.000 ft (this means an IAS of about 600
kts...!!!!)... and keep that IAS during a shallow climb. Adjust the
climb rate accordingly - most important is to keep IAS. The higher you
climb, the higher gets your MACH - until you level off at 70.000 ft
with an IAS of abpout 600 kts at Mach 3.x.
