I was looking at purchasing the Holley 1850 C 600 cfm but the linkage connecting the accelerator rod is different than the stock Holley carb and when I looked at the 1848 465 cfm linkage appears more stock. Has any one modified the linkage and has it worked for others? I wanted to get the 1850 but if I don't want to run into a problem hooking it up. Application would be for a 1960 ford truck with a 312. Appreciate any input.
