Based on the fact that you're many times the size of the Black Mamda, you should be able to kill a dude in five minutes.

Speed of a toxin does not change according to the dosage, it changes according to the toxin and how fast the heart is beating. he is still a black mamba, and thus still has the same toxin, though he can strike several more times in a row, a lot faster, and can deliver deeper in to the body, actually from the observations made, he should be able to deliver directly to the heart itself with a chest strike.
