I just bought a new 600 cfm holley for my 390 because i had a 750 cfm and it didnt work for it and now the 600 is working EXACTLY the same as the old one. Its backfiring out of the top and bogging down. I was told to buy the 600 because it would be a good match for my engine but im really starting to wonder now.

I put it in the way it came out. Is there anyway it could be backwards or something?
