I have an 87 5.0 just installed a BBK 70mm Throttle body, put the new gasket on and for some reason it ran good for about 10 seconds then chugged and stalled... There are two radiator lines running through the intake manifold, don't know what they do (first mustang lol) but its filling the intake manifold with radiator fluid and spittin it out the exhaust, I am not going to turn it over till I figure this one out... If anyone knows why maybe its doing this I would rep greatly!!! I'm going to Atl dragway tonight so sooner the better THANKS BRIAN
