I'm swapping my tired 305 for GM's 330 HP 350. I got the old out and went to go back in with the new when I found out so dismaying news. I went to put the exhaust back on and the passenger side manifold wont hook up. The stupid thing is a half inch off or so, which is funny cause the driver side went on fine. Does anyone know where I can get one of these for a reasonable price. I found the driver side at scoggins dickey, but no passenger side. I would go back in with headers, but I don't have the money for the ones I want, and I need to get the thing running. Thanks for all the help.
