The factory cam was small. The only Dyno numbers I can remember on a 273 Commando I was involved with, was 265 HP with 2 barrel pistons, an Isky E-4 cam, and an Edelbrock 600 cfm AFB. I don't put much stock in Dyno numbers.
I wish I had the opportunity to dyno mine but the shop in town had been sold and the dyno wasn't set up in the new shop yet. If I were to ever pull it for any reason I would run it down and hook it up. Just to see. Curiosity more than anything.
