273 4bbl dyno results

I was often curious if Chrysler under rated the 273 HIPO HP

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.
