Be good to know what's sruck or why. If just rings put oil, ATF, WD-40 in the cylinders & let it soak. bought a stuck 331, turned out the cam was locked solid.

It’s a Engine in one of my 58 Dodge Mayfair Convertibles ,It’s no telling How long since it ran ,the car rolled on its side then Top so I assume it was running prior to the wreck .The Engine was originally in a 1958 Dodge it’s a 354 Poly Engine .Its a clean Looking Engine .

Yeah typically i would disassemble.
Take caps off, timing chain, see what moves. Start punching pistons out being VERY careful with passing, tape upe anything to protect crank.

For rusted/stuck rings, there are some who swear that soaking with Coca-Cola is better than any accepted solvent.

There was phosphoric acid in the Coca-Cola in the old days, perhaps still, but surely a much lower percentage.


Phosphor acid is a very good way to remove rust, the downside is that it'll eat up steel as well, so one must keep attintion to the process and never leave it on for too long.

I'd just squirt some oil, 30w, 10-30w, in then after it sits a day or two breaker bar and socket on the crank pully rocking it back and forth. Best bet is the rings are stuck, don't use a lot of force. Hopefully no water got in it. If that's the case probably gonna be driving the jugs out with a good hammer and a 2x4.

be very careful, I mean if you care about the engine... people start bending rods.. scratching cranks...


you cant give this stuff away but when you need a part, you can be in real trouble. Were working with unobtanium...


You cant just buy a crank or a rod at a local shop and you are talking about a whole machine shop rebuild then also and balancing etc...

This is what I use. I work at a dealer so it is easy to come by. Works very well on all rusted items, like brake line fittings also. Even though my 361 turned over when I got it (sitting since 1975!) it had some sticky valves. This worked well to free them up.

Thanks for Everyone’s advice ,over the winter I’ll be letting it soak and hopefully it will free up .The Engine Looks very Clean and Dry but my Guess is in hasn’t run in many many years ,Im sure it was a Good running machine before it rolled over at least I know why they stopped Driving it .The Fuel in the Tank was the Least Combustible gas I ever ran across .

Acetone is a very volatile solvent. It will push through any kind of crack it can get to. That's a good thing in this case. So make a 50/50 mix of acetone and transmission fluid. Put it into the spark plug holes and put the spark plugs back in to prevent evaporation. Let it soak. The Acetone will push past the rings and take the oil with it.

Acetone & Transmission fluid is very good. I'm thinking that recirculate hot water through the block might help as well.

Thanks Nathan I’ll give that mix a try ,Looking at the Engine I don’t think it’s stuck that bad the car was in Heated storage for a while and the Engine looks Good .Are you Farmiliar with the 354 Polys ? This one was out of a 58 Canadian Dodge and put in one of my 58 Mayfair Convertibles How Do they Compare to the 318 Polys ? Thanks.

I am familiar with them. I own 2 of them, one that I got running after it sat in a field since 1979, and the other that I got running after it had sat for an unknown amount of time. The first one is the strongest motor that I have been able to revive. They are great motors. Just install a good 4bbl and dual exhaust, and they will impress you. Definitely a noticeable step up from the 318 poly in terms of power. '58 is the best year for them too because the compression is 10:1.

George ,I also thought of Converting it to a Hemi but Don’t know how much trouble it would be to find parts for it.

I agree with Nathan. I have rebuilt 3 of them and regard them as my favourite early Hemi/poly engine. The 58 (domed piston one) is the best and, BTW, the 2bbl version, which was standard on 58 CDN, Custom Royals is a great road car for driving today. My experience is that you will likely get better fuel economy from the AFB but the off-idle throttle response of the 2 bbl is awesome!
They, just like the hemi, will run very well on crap gas even with that higher compression ratio.

Thanks Greg for the input that Engine has been in that car a long time ,And I assume someone might have swapped it in the car for better performance maybe that’s what Lead to the car ending up on it’s roof and they stopped Driving it ,I would love to know what year that happened.

Especialy with the 413 engine in my Letter. The first piston was melted at the top and the skirt to the cylnder wall. I could remove everything except the first piston. A cylinder grinder cut it into three parts and removed each fragment after each other. I saw the removed piston... good luck guy knew what he did. He saved the cylnder wall.

Happy Restoring!

If the car rolled over while the engine was running it probably quit running because the sump was empty and all seized from lack of lubrication. Just a nasty thought to rule out!! I once bought a 315 Hemi with a similar history!

Greg is right, if it was running when it rolled it will likely have some damage and possibly the reason for being stuck.
I'd suggest pulling the top end and having a look-see at the cylinders; possible rust issues will keep it from turning.
Then pull the pan a check the crank for a seized bearing.

No advantage to converting to Hemi other than bragging rights. The Spitfire is a strong runner in stock form.

When I wrecked my '56 Chevy 4x4 suburban down a steep ravine with the back end up at a 75 degree angle, I just pulled it out, pulled the fender away from the wheel so it would roll, re-filled it with oil as it had all drained out, and drove it home. It would be very unusual for a carbureted motor to continue running in a turn over because the fuel would dump out and it would naturally shut itself off. But fuel injected cars are a different matter. So he should be fine in that regard.

Edit: Even fuel injected cars would likely shut off due to the interrupted fuel supply at the tank. They require a constant supply to keep running.

Something I get from NAPA is called "Mystic Metal Mover". I use for oiling when drilling and other stuff. Haven't had any bits start smoking using it and it works good on rusted bolts too. Another one is metal blaster at Home Depot works pretty good.
