High idle after intake change
Good morning/day all,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

I just recently replaced my intake and put a rebuilt 600 cfm carb on my 360FE truck. Anyone have Ideas of why it will not idle down. It is pulling 17.5 inches of vacuum I have tried to adjust the timing but still not quite right. The intake is a F427 edelbrock and the carb is a holly 4160. The sad part for me is My truck is at home in GA and I don’t have room for it with me in IL where I am stationed.<o></o>
Any and all help will be great.<o></o>
Thank you<o></o>
Very Respectfully,<o></o>
