beefman Posted February 3, 2021 Share Posted February 3, 2021 Hey Folks, I very randomly post on here, but I read quite a bit. Long story short, I was given a Holley 4bbl carb tonight (came off our fire department’s old IH tanker truck when we switched to FiTech EFI last year). I don’t know squat about Holley’s, I barely know enough squat to work on the 2150 that’s on Big Red right now. While it’s not exactly in the plans for Big Red to get a 4bbl, if I came across an intake it might end up there. I’ve attached pics of the carb. The only identification on it are LIST - 1850 - 3, and 2508 below that. I just want to make sure that I’m identifying the carb correctly as an 1850 and getting the right rebuild kit when I want to do it. Thanks for all the helpful information I get from y’all!

85lebaront2 Posted February 3, 2021 Share Posted February 3, 2021 1850-3 is a later version of the old R-1850 600 cfm, originally used on 1958 Lincoln and Mercury 430 ci engines. The 1850-3 was a hand choke version with a "universal" (read Chevrolet) throttle shaft. Link to comment Share on other sites More sharing options...

If I’m reading Chevrolet throttle shaft, I would guess there’s some mechanical magic to making it work on an 84 F150 with a C6? As long as it’s not out of the realm of possibility, I’m fine with tinkering to make it go. Link to comment Share on other sites More sharing options...

You need one with a Ford throttle ball and a connection for the C6 kickdown rod. Link to comment Share on other sites More sharing options...

I used to keep a few in stock at Preston, the kickdown lever was the piece you had to have for an automatic transmission Ford. Link to comment Share on other sites More sharing options...
