NHRA Horsepower Ratings for the 273

Tool Man Mike,

We ran a 273/235 HP Commando back in 1967, with a 67' Barracuda Fastback.
And ran it from 1967 thru 1971 in Stock Class.

Since we bought the car 'practically new' in 100% stock trim, we had a chance to
have it tested on a 'new' Bear Dyno Machine.

I can't remember the exact numbers, but it was not near 235 HP @ 5200 RPM
'at maximum level'.

I'm assuming this was an engine dyno, not a chassis dyno, correct? I'd love to see a HP/torque chart just to see at what point these engines started "falling off". I always thought with the 4-barrel carb, open plenum intake, solid lifters and the dual point, they'd be good for over 6500 easy, if not 7000.
