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



Yes your fact about the Holley carbs venturi size goes along with my statement that the Edelbrock Carter and Quadrajet carbs will not make the peak hp of the Holley. Every last ounce of HP was not the goal for my cars. The simplicity and great performance with a little tweaking (step up rod springs changed and maybe acc pump shot adjustment) with the Edelbrocks is a big reason I suggest buying them. I was not willing to run Holleys only because they would not simply bolt on to the low profile dual plane intakes I ran. With a tunnel ram fitment is not an issue.
