Hey, we have a 239 yblock from a F350, just wondering if the Y block,another 239 but from a car, would be worth it to pick up for a parts engine. If you could let me know that would be awesome!
If you plan to keep it as original as possible and it is also a 1955 239, absolutely. 1954 239 are in many cases not interchangeable with other Y-Block parts.
If you want to upgrade, then the money will be better spent on a 272, or 292.
Refer to this site so you can identify what you have and the engine you are considering to buy.
Alright, so we have the Y block cleaned up now, rotating freely with the valves relapped and decent enough compression, mostly 100-110, with one weak cylinder that needs run in again to reseat. Wondering if anyone has down a carb rebuild kit out there. I have found a float to get but I haven't been able to find a gasket kit. Would one of you fellas know where I might find one?
It's a 3-bolt 2 barrel, so Holley 94 or Stromberg 97. I don't know where to find kits, but given their popularity, they should be pretty easy to find.
Edelbrock also make brand new 3-bolt 2 barrels.
Stromberg still make them.
Those gives you more options.
The compression is pretty bad. If the numbers don't come up after it's been run for a while, get ready for a rebuild, at which point you should seriously consider upgrading to a bigger Y.
Thanks for the info Charlie, I think I may have found a kit that will work, just wasn't 100% sure on which carb it was till now. As for the compression it's not going to be a race truck, just needs to drive a couple of miles back and for a couple times a year is all. But those numbers should come up after the engine has been run a little bit to reseat the rings again.
Mikes Carburetors has kits for just about everything, and free manual downloads for everything in .PDF form. He even answers email. There are other good websites too, but it's easy to remember.
Yeah I forgot to mention he has quite a few YT videos on disassembly and rebuilding. Carbs are pretty easy but there are tricks and a few gotchas on some of them. When a carb is setup and tuned it's a beautiful thing. If not, not so much.. lol
Would have been nice but their engine wasn't in the best shape. So we opted to just repair our own parts and continue. Waiting for the carb kit to come in now and should have the old girl whirling before we get too into spring time (I hope). Depends how much time off I will actually get to work in the shed

I am not an expert but isn't compression of 100 to 110 pounds good for an old Yblock?
