22” radiator, do they keep up

My rad is a factory 26" A/C rad that was new in 1973; and is mounted in the 22" opening. With the other cooling mods most of us do, it hasn't given me a lic of trouble.
The engine is just an HO 367 tho, with a 230/237/110 cam. Same set up using the 292/292/108 also worked fine. I run it at 207*F on purpose, using a thermostatically controlled clutch on a big 7-blade fan, in a tight shroud.
