304 popping

Just put a 304 in my yj but I started it up and it is popping really bad out of the carburetor and shoots a flame out if the exhaust at the same time! Not sure what it could be! Any help would be appreciated!

firing order is 1 8 4 3 6 5 7 2 ..it is a clockwise rotation..cylinders are numbered,driver side,front to back,1 3 5 7 ..passenger side,front to back,2 4 6 8 ..double check them because all it takes is for 2 of them to be swapped to cause it
