strange my edelbock 600 worked realy good on my 318 and when i built my 340 i tried holley and holley is the worst piece of junk i have ever been dealing with.... gave up the holley after a summer full of trouble and put on my old fuelleaking greasy carter AFB and it fired right up with realy nice idle and the trotlererespons is awsome! now i have an 800cfm edelbrock Thunderseries avs that is working perfekt to!!!
but it could be my car that has an alergy for holleys...
