It kinda looks like I'm not going to find a 600/650cfm carb for my
305 build ... so I'm faced with deciding which of the 2 carburetors I have on hand is going to be the best choice . I have a 750 Holley vac secondary with manual choke that I've been told is too much carb for a 305 motor . My other choice is the stock Quadrajet , but I'm not sure it will support the potential of the mods I'm doing to this motor . Another negative for the quad is that I'll need to buy or fabricate an adapter plate to mate it to the square pattern manifold I'm going to use . I have rebuild kits for both units and time to decide , and who knows , that ideal carb might just fall into my hands before I need it !- posted
