work has been few and far between on our 60 f100, but it has been happening. the source of high idle has been found (vacuum leak, and a home made linkage piece)but now that all that has been sorted out the weak link has exposed itself the 223 has a stock 1904 holley carb that i rebuilt, the float has broken twice due to. . .i honestly have no idea, but trying to find parts for the damn thing is near impossible. and on top of that it was never in good condition to begin with, half the holes are stripped. so in the hopes to have this truck on the road within my life time, would it be safe to trade the 1904 to a 1960 carb? or what carb would you recommend to switch to? thanks!
I had a 1904 on my '63 Scout, I ended up swapping it out for a Weber 32/36 using an adapter from Langdon's Stovebolt. Electric choke and electric pump woke that right up on cold starts. Heres a good read http://www.justih.org/Binder-Bench/showthread.php?t=8971
I run a 1904 on 56 223. I too had some challenges working through various issues. Ended up picking up parts carbs off of ebay. I still see the 1904's listed frequently there. Regardless, I think the 1960 is similar enough to work.
You can get 1904 parts carbs from wrecking yards,eBay and even Craigslist. I see them pretty often. I'd say just stay with it.
1904's(or variations thereof) are just about dime a dozen, they where used on alot of vehicles. I would keep an eye out at a swap meet and your sure to find a couple for cheap. Alternatives include the Autolite 1100 which came on later 223's and small block Ford six's and maybe the carter that came on the Dodge slant six not sure about the Dodge but I do know they used 1904 type carb for a while and then switched to the Carter. That being said a 1960 should work, as far as I can tell they look the same as a 1904. But thats just from a few minutes on Google. The bolt holes on these things strip out like crazy, chief of which are the screws that hold the bowl on. On mine I just ran a small bolt thru and put a nut on the back. Not the best repair, but it hasn't leaked a drop in the year its been like that. Helicoil's are also an option.
Mopar used the 1920 as a mainstay throughout the 60's, and it's a very close cousin to the 1904. The slant six was also a 225" engine. Roger
