Intake/Carb Question
So I'm new to all this but trying to learn. I have a 1968 F-250 with the 390. It currently has a 1965 Ford 4V intake and an Edelbrock Performer Carb (with adapter plate). What it is the correct style carb I should be running on it? Spreadbore or squarebore? I'm not trying to hot rod it or anything, just keep it as a solid work truck with good bottom end and midrange power.

Now, which carb is it? The Performer (Q-Jet copy) or the AVS (the Carter AFB copy)? And what size/brand cam are you running? I was thinking of going with a 625-650CFM carb with a 272/272 cam. And I'm running a Dana 60 with a C-6 trans. I think the gears are the original gears which were 3.54 from the factory (according to the build codes).

A 600 cfm manual choke Edelbrock is PN1405 and the electric choke version is PN1406. The FE Edelbrock Performer dual plane intake is PN 2105.
My FE inhales through the 1406/2105 combination with a 1-inch phenolic spacer and exhales through Hedman Hedders PN 89120, 2.5-inch tubing, and Moroso Spiral Flow mufflers. Works great.. the headers and exhaust really woke it up.
Square bore is the what you will end up with.

Thanks HIO Silver. I have the 1406 version. But, does Edelbrock make a kit or something to refit for the A/T Kickdown?

Yep. Summit has a kickdown kit for C6 and C4 trannies - PN 03-0043 and 03-0044 respectively. The kit consists of a throttle cable, bracket, linkage, and the kickdown cable.
