What 340 camshaft?

I see that the lift is over 0.500 on this cam. Duration isn't terribly different, Except the exhaust (compared to the 275DEH.) Cam like this might do better with an 800 carb?
I’m sure it would do better with the bigger carb, in a street/strip application. But with a strictly street driver, I don’t think it would make a difference. With your 10.5 compression, rear gear, and the relatively low duration of that stick, I think it would make a real stump puller.
