408 carb question

I wish I knew exactly what cam is in it. When I say mild I kinda mean fairly stealthy. Idles hard / drops hard . I should get ahold of the guy that had it built. (Lost contact) , what I should do is just get a 750 and see what happens. Can always sell one of them or keep it like the rest of the junk I have. I probably would buy that carb off you Winstoninwisc but by the time I pay for customs and shipping to Canada I will have a brand new one.
