Flathead in a '53
I posted this on the flathead forum but thought I might get more replies here.
I'm going to look at a 1953 F350 this weekend if the weather cooperates. The owner has sent the picture below of the engine. No known history, no telling how long it's been sitting or the condition when parked. The truck is in an old salvage yard, so it probably had some issues of some sort.
Anyway, I'd like some advice on what to look at, check, etc. on the flathead motor before laying out some cash for the truck. The owner keeps stressing that "it's a flathead" and I'd like to know a ballpark of what a flathead with no history is worth. From the pic and owner's description, it's complete.
Based on the condition of the rest of the truck and the fact that there is no title, I would be buying the truck for "parts only." The grill looks pretty good from the pictures and I have a '54 F-100 that I could convert to a '53 if the motor turns out to be a keeper.

Thanks a bunch!
Oil in the crankcase and normal in color? Probably dark but as long as it doesn't look milky its probably ok.
A flathead with no history is a potential boat anchor. This one looks very stock. IMHO that flathead, without a chance to pull heads is a $100 possibility. You could likely clear $100 if the block turns out to be cracked and you have to part it out.
If it turns over - a little more maybe. If my above criteria are met then I'm in the neighborhood with Ross.
fwiw, I have a cracked block that under pressure will suck the entire 5 gallons of coolant thru the #6 cylinder and out the exhaust in about 5 minutes. I loosened the rad cap and pulled the thermostats out, then ran it home by adding water as needed. The trip home was from central Illinois to nw Montana back in '01. About 1500 miles.
Point is: just cause its sitting there doesn't mean its a viable engine.
I don't think you should plan on going to a junkyard to drive any truck away. You go to a junkyard to buy parts and to buy restoration projects (such as this truck).
Flathead motors are expensive to overhaul because of the parts prices. Machine shops that do flathead work are scarce. Overhaul usually run about 3000-3500. You can get 2 Chevy 350's or 1 1/2 302's done for that kind of money.
If you are lucky and you pull the heads and find that there are no cracks from the valve stems holes or piston bores or the exhaust ports when you pull the heads. You should have a salvagable motor OK for overhaul. I think the percentage of as salvageable motor are about 50%. The percentage for it to be not frozen, and to be able to fire up afer a quick cleanup etc are less than 5%.
However, I still think it would be a great project.
Good luck. Let us know

All I have seen so far are pictures of the truck. It's ~2 hours away and I hope to go take a look in person this weekend. The asking price is a bit more than I would be willing to pay for the truck sheet metal parts alone. The owner did tell me last night that it has been in their yard for ~10 years and the engine ran when it came in, but didn't know anything else about it. With the info you guys provided, maybe I can convince him the engine, although unique, is very "iffy" for restoration.
The truck has no rims/tires, so what is the bolt pattern for a '53 F-350? I'll need to locate some "loaners" to get it loaded on the trailer if I choose to buy it.
Thanks for all your help!
