Me thinks those that advocate using the Eddy or Carter 500 or 625 or 650 CFM carbs aren't thinking of the uneven air flow through the smaller primarys on those carbs Not so on the Holley 1850 Same thing on the Holley 650, 750 and 850 D.P. carbs, same flow through all four barrels



sure its something to consider(but following that logic forget about anything that dont have 1:1linkage betwen primary and secondary aswell leaving you pretty much with 660 centersquirters as the only option),but considering the original posters intentions i believe the 500cfm edelbrocks would be a good choice,since these carbs dont need much work to work good and they will be real snappy when just cruising around on those small primarys linked 1:1.
got a good friend that did a straight swap from an Airgap and a wellsorted out 750 proform to a tunnelram with 2x500cfm edelbrocks and with the carbs straight out of the box the thing became alot sharper just cruising around and uses alot less fuel,its dead reliable and will start with just a quick twist of the key
