Sounds like a ruptured fuel pump diaphram

If the fuel pump diaphram is intact, then I would think the fuel is coming down the cylinder walls. Is the car hard to start, or prone to flooding ... RUnnning really rich? ... If so, I would re-visit the carb, check the floats, and make sure that the fuel pressure is not too high ... might try going back to 6 psi ...

thats what I am thinking that the carb is not set right, if i let it sit for a few days then start it its great,I just picked up a 850 DP do you think that may to munch for a 406, the desk top dyno said it should have a 900+ what do you think.

From what you list, it doesn't seem that the 850 would be overkill ... Still, expect to have to do some carb tuning ... That will probably fall under the category of try and try again ... Afterwards, I suspect this thing will pin you to the back of your seat and make your eyes open wide! ... ought to be a blast to drive ...
