i run a 4v on my 289 (650 cfm holley) and when i bought that i bought the edelbrock rpm performer airgap intake, better than a later model intake cuz cool air can flow under it and as we all know, cold air = POWA!!
im assuming your talking about a mid 80s 5.0 carb intake i dont know the flow numbers off hand but its probably know where near a weiand or a edel etc.
