I wouldn't mind a dyno sheet on my 273 just to have it, even if the numbers are disappointing. If I build another engine (doubtful) I will spin it up just to see what it does.
If I were to engine dyno something, I truly believe it would be a stone-stock 318 2bbl to see if I could tune/time it to the 230 "advertised" hp. That would be interesting.
