I bought my Crown Vic with 3 Holleys on an Edelbrock 573 manifold.  The front and rear carbs were blocked off.  The car ran fine.  My problems began when I tried to unblock the front and rear carbs.  So, I pulled them off and sent them to a well known carburetor guru who specialized in old Holley and Stromberg carbs.  Got them back and it was much worse.  Sent them back and he said he found some mistakes and corrected them.  It didn't work.  I blocked off the front and real carbs and that did not help.  I have called him and he says they are fine, the problem is somewhere else.  I bit the bullet and bought a new 4 bbl manifold and Edelbrock 4 bbl.  The car now runs fine..  I am sending them back again, but somehow I don't expect to get the issue resolved.  Don't tell me to just keep the 4 bbl.  I want the old fashioned tri-power set-up because I am old, stubborn,  and nostalgic.

Any suggestions on where I should go now?  I have over $1000 invested in those carbs.

Thanks guys
