It is approximately 6*’s more duration @ .050.
(Figure a few hundred more RPM’s that what you have now higher in its operating range. What it will be exactly is hard to predict and say.)
Is it livable on the street? That becomes a question of ones limit and comfort ability. You could possibly still use your current gear set (ratio) and stall converter, if it is loose. If it is tight, one of them will have to change. I’d go for the gear set first.
What’s your gear ratio now and is the next one up to much for you?
I know people that have cams in the 272/282 intake duration @.050 and are fine with it.
