EDIT: Out of respect for this 1968-1972 group..please forgive me. I erroneously posted the following here instead of as in intended in the 1948-1956 section..Even so the advise etc HERE in this section has been great. I have also decided "to pass" on the engine I originally posted on. The seller showed that he WAS NOT CREDIBLE (aka FOS) the engine was for SURE not in a pickup. Motor mounts , t stat and air cleaner are from a car cica 1955 NOT a 1958 f100. Prior post b4 the diclaimer: Ok I'm wanting to get another engine to either build up or find one that I can use while I build this one.... or? I have located what I was told" My father passed sometime ago and Im cleaning up stuff...this engine was in my dad's 1958 f100 truck 30 years ago...he had a automatic transmission problem(the torque converter is still attached) and removed the engine to rebuild everything and ended up selling the truck"...the son does not know anything more about this complete engine. The block indicates it is a 272. so does the 2 barrel intake casting number. On my asking, He removed all the plugs and tried to turn the engine and it did not rotate. He was afraid to go further and maybe break the crank bolt...The engine is and has been stored for some time now in an airplane hangar where the son works doing airplane mechanic type work so he has some mechanical ability...He was originally trying to sell this for engine as a "make me an offer starting at $500". What's its worth now that it appears seized>? The engine sits 2 hours away from me so going to look/get it etc is a factor also The engine is very dusty looking like it was out in a field somewhere from the photos...."I cant swear it hasnt been exposed to water. although the air cleaner is still on the carb." I said "with it seized like it is MAYBE half of what you were asking if I really like what I see"... He was ok with that. he is not willing to do any more than what he has done already especially for the reduced money this is going to bring him now...Is it worth $200? and 4 hours to go after it?

 

I would say pass. I've heard so many stories saying "that's all I know" about something. Part availability could also be a problem. Why not invest in a nice crate motor?

 

Unless you can hear it run, an engine is basically a core. Even then... You are exactly right to offer around $200 or so. I'd have Tim McMaster - the Y Block Guy - build you up an engine. He's in your neck of the woods, no he isn't giving them away but he knows all the minutae and "gotchas" and will have a ready to run engine for you.

 

I am gonna go with no. If it was a small block 289/302, or some kind of FE motor I would most likely say yes. I have never seen/heard of some one putting a Y block in a 67-72 f-100, but that does not mean it can,t be done . If that is what you are thinking.

 

May I add my two cents?

A seized engine is a boat anchor. That being said I've seen many folks buy seized antique hit n miss engines that sat outside for decades. First thing they did was remove the spark plug and pour diesel fuel in until full. And just let it sit for weeks. And since the crank bearings were exposed, they got soaked in diesel too.
Many times with persuasion these engines could be freed up. Sometimes not though.

I do agree with all above. Give no more than scrap price for this engine, which would be around $100.

But I would pass. Plenty of unstuck engines out there.

 

No 272's in cars after 1957, in trucks after 1959. No Y blocks in cars after 1962, no Y blocks in anything after 1964.

Y blocks in trucks mount completely different, so don't plan on bolting one into a 1965 and later truck.

 

I would pass on it. $200 and 4-6 hrs of your time seems to be excessive. I recently bought a '63 F250 at a farm sale for about scrap price (the body is very straight and solid though). The 223 in it is stuck and have not been able to free it up yet. My next step is to pour kerosene in each cylinder and let it sit over the winter. I knew it was stuck when I bought it but the body was worth well in excess of what I paid for it.

 

The sellers Story is now fishy also..ill go have a short block built by Mr Mummerts builder..Ethyl's recent rebuild of the cylinder heads was eye opening enough for what can go wrong if you dont have experience...i wonder if Mr Mummerts builder will LET Me under his watchful eye put together my engine...guys i also have the ask forgiveness here I posted here instad of in the 1948-1956 section by mistake...still received really good advice though..I monitor both areas of FTE hoping to learn all about my 1972 f250 aka Brutus so when he's finally out of the paint shop and Im driving him..Ill be up on stuff this is Ethyl *THE* ToolTruck

ETTT 1955 C600 Rolling Tool Store

I love the USA....

 

....or consider...I have an original, never been rebuilt 352 out of my dad’s 66. I upgraded it to a 390 when I restored it.

 

Thanks..I want to stay period correct. I too would do a 390 if gasoline or 460.but if I do change more than likely a Cummins 12V 5.9 will be the choice.
