If you have even just a multi rating, you are covered. Prime example of grandfathering; I had a fair amount of time in C-421's before there was ever a high altitude sign-off. So I never needed to get that sign-off for high altitude and pressurization.

The high-perf endorsement is for aircraft with MORE than 200 H.P. Used to be an Arrow would qualify, but no more. The Arrow qualifies, as well as the Mooney and others, for a complex, because of the retractable gear.

I started flying in 1973, forgive me now cuz I am old, but I do seem to remember that the High-performance and complex were generally signed off in one endorsement back then.
