My 65 289 coupe has been sitting for two years. I didn't start it up periodically like a dummy. Now that I've finished most of my upgrades to my car, I now want to get it started up.
It has a new sending unit clean tank fuel lines and filter. I poured in some premium fuel with some berrymans addative. I how ever was stupid and flicked the ignition 3 or 4 times hopefully I didnt damage anything. I have now added some marvel mystery to each cylinder and I am letting it sit. I was going to let it sit for a few days to see how it loosens up the Pistons and rings. I plan on taking off the distributor cap. Then using my breaker bar and socket and gently try and rotating the crank with the plugs out. Are there any suggestions some of you may have for me as well?

After sitting for just two years I wouldn't worry about it that much. Has it been in a garage the whole time?
I would say its extremely unlikely that the engine is seized. Mine sat for much longer than that at one point and I simply drained the gas and refilled it with some fresh fuel, put a new battery in it and fired it right up. I ha an engine sit on a stand for over six years one time and pulled the oil pan and looked in the chambers with a bore scope because I was paranoid about corrosion, etc. Zero, looked like I'd built it yesterday, and that sat in my shop which is neither temperature nor humidity controlled.

I would remove the dizzy and prime/pressurize the oiling system...also prime the carb with a little drink of fuel just before cranking to start....jj

I broke in my motor but then didn't run it again in the car for a year in dry no humidity Cali. I too put some Marvel Mystery oil in the cylinders, let it sit and rotated the crank. Primed the oil and fired it up. I'm sure I had at least one cylinder with stuck rings as there was pretty good pressure coming from the valve cover holes and dip stick tube. The pressure dropped considerably after 30-45 minutes.

The car was parked out side for two years, but it was covered. The only reason why I was a little worried the rings were sticking was because when I flicked the ignition switch. I didn't see the fan move very much but I heard the starter engage. This didn't seem normal. My dad was saying he thought my timing is probably off. I didn't ever seem bad before when I parked it. Mine is a vacume advance my vacume advance is almost all the way over almost rubbing the thermost housing. One thing I'll need to purchase for my car is a timing pointer. The new timing chain cover on my car doesn't have a forged in pointer. I'm going to have to purchase a pointer for it as well.

Once you use the breaker bar and remove plugs, you should know a lot more. If it rotates you should be ok?

I agree with the other posts that you should be OK following your plan.
Regarding your distributor, after you get it up and running, pull the distributor and move it one tooth. As for the timing pointer, as an temporary fix, fabricate one from a wire coat hanger and attach it to a timing chain cover bolt, bend it to the timing mark.

So i haven't let the marvel mystery really soak. I did give the crank a slight pull but not with any real effort. It moved a little and I mean maybe a quarter inch or so. It probably could've went further. But I don't know how much resistance it should have. I was thinking about getting a flex plate wrench to try and also rotate my crank. Should the engine have some good resistance?

If you want accurate timing you need to truly know where TDC is, and you're not going to get that without a little work. On an assembled engine the best way is to use a piston stop threaded into the #1 spark plug hole. Rotate the engine clockwise until it contacts the stop, mark the balancer. Rotate the engine counterclockwise until it contacts the stop, mark the balancer. The point in the middle of those two marks is true TDC. This sets you up to easily use a timing tape so you can be dead sure of your timing.

When you're finding TDC, make sure you're on the compression stroke.

Should I remove the starter before I try a socket and breaker bar to move the crank?

What ever you do don't hit the starter with the breaker bar on the crank and make sure to disconnect the battery just to be on the safe side.

I wasn't thinking about hitting it. I was just thinking the starter was maybe stuck. thus making it harder for me to use a socket on the crank to move it.

Odds that the bendix in the starter is bad are extremely long.

Good to know. If the internals are all right in the block should I have to use some force to move the crank or should it move fairly easily?
Offline
With the plugs out it should move fairly easily, but you'll have to put some force into it to overcome the ring drag on the cylinder walls.

Awesome I'll have to try and move it tomorrow. That will be about the third day that I have let it sit with some marvel mystery oil. Thanks everyone on here for the help suggestions and guidance. I'm hoping the 289 in it isn't trash. Other wise a new engine will be in my list. or to have the block remachined this is what I'm looking at or for a new long block 302 I can have one shipped to my house from eBay for $1,200.

I'm a real believer in "you get what you pay for" and after building a few engines I would never even consider a $1200 long block...or a short block either these days. Shipping alone will be $300 to $400. That doesn't leave very much for "good quality parts and workmanship", IMO.

I hear you on you get what you pay for. The 1,200 was with shipping. But still I'll have to look around more. I'm just hoping I can break my 289 loose. I'm only the third owner. The first two were father and then he passed it down to his son.

Question... Could my torq converter be seized? Im wondering because maybe its not letting my crank assembly move freely?
Offline
I might be chiming in a bit late here...
When I bought my Mustang, the guy had it sitting in his back yard with a cover. I think he didn't start or run it a good two years (maybe longer). I had a tilt tray truck transport the car to my house and remember all four wheels being locked up and the car sliding down the tray when he tilted it. I had to beat the drums off the car and rebuild the brakes. I had to put a new fuel tank, fuel pump and carburetor on the car. This is going back nearly 14 years ago now, but I would have made sure engine rotated before firing it up. In the end, it fired right up and not long after that, I had to do a 5 hour drive in it. My personal opinion is that these old engines are pretty tough

I've never heard of a torque converter locking up, so I find that unlikely.
Spending $1,200 on a long block from Ebay; you'd be better off to just set that pile of money on fire. When it comes to engines you absolutely get what you pay for. If the engine needs to be rebuilt I would simply contract with a local machine shop and have it rebuilt. Worst case it needs to be bored and a set of new pistons. In the end that's likely more economical than a $1,200 "new" engine anyway, especially if you can do the disassembly/assembly yourself.

Sounds like your having a tough time getting any rotation? How long is your breaker bar? Did you prime your oiling system by removing the dizzy? Priming the eng. w/ a drill will get the oil pump flowing oil throughout the entire engine so everything get lubricated inside. It should help getting this moving.

I haven't done that. So I need to remove my dizzy and do what sorry? I was able today to finally get a little movement. I was using a 18" 1/2" drive breaker bar. Now I took off the crank gear pully. And now I made my own wrench out of a 24" piece of black pipe and a 3/16" steel plate that I welded together. I have that wrench bolted to the fly wheel. Now I have been rocking my bar back and forth. I was able to get a little rotation out of the crank. After I was able to move the crank a small amount. I poured in some more penetrating oil down the spark plug holes. I've gotten the best movment out of the crank with this new penetrating oil that I've been using.
