Engine Block Number- Need Help Identifying Please

[fourleaf]

Gents, i have my p-15 at the shop getting some of the final parts on and it should be done today. I bought a oil pan gasket to put on and it was to short. After looking at the motor on the lift today the motor that is in the car is not the stock motor unfortunately. When I bought the car I noticed that the frame had been boxed in and was wondering why. That explains it. The motor block number is C53-6666I. I have look on the Internet and can not find this number anywhere. I was wondering if I could get your help indentifying who made this motor and what year it is? The census in the shop is a dodge 50's motor. I had them go ahead and make a oil pan gasket from scratch today. Thanks for your expertise in advance!

I would say the shop is wrong and that you have a Chrysler motor. Also a dodge 6cyl would be the same length as your ply had originally while the Chrysler and Desoto were 2 inches longer. If its expensive to have them make one you should be able to get a pan gasket easily by ordering one for a Chrysler.

How long is the head on your engine? 23" or25"? Where on the engine did you get the engine number?

Thanks Ed, the motor was to long so they had to cut some of the plate near the front off to get it to fit. That's how we noticed it so quick. Your right though, they would be the same length. This one has the spitfire head on it with the trans matching up to a 40' 50's Plymouth.

Just do not know what kind of car the motor came out of.

Ed, not sure how long the head is. I will,have to call the shop to get that info. The engine number was on a lip underneath the head on the block.

[Don Coatney]

Spitfire head is a giveway. Only Crashlers have that head. If you can find the year of the engine you may have a 265 CI engine. I hope the guys that made the pan gasket know to not trim the excess for the end pieces.

 

Also how is your tie rod to oil pan clearance? I had to mofify my oil pan to allow proper clearance.

No need to call them. A spitfire head is 25 inches

Where did you find this car? Did the prior owner tell you anything about the engine such as when and where it was installed?

 

I had to modify my front crossmember to make a 25" engine fit my P-15.

And the oil pan being too short confirms it .  Could be a 251 or 265 depending on year, the 265 was 53 and newer.  Cool beans if its a 265 and is sorted to its space.  You can check the stroke by pulling the little plug in the head above cylinder #6.  Insert a piece of stiff wire about 8 inches long and turn the engine over by hand,  The wire will ride the piston up and down and you can measure the distance to the bottom if its travel.  4.5 inch is 251,  4 3/4 is 265.

 

external parts and accessories should be the same for either engine.

C53 designation is for 1951/1952 Chrysler 8 (Crown Imperial)

 

If you only have 6 spark plugs, I guess that is no help

I was told this car sat In a garage under a cover for years. The gentleman who had it got sick and told his friend if he wanted ithe could buy it. But first, he told his friend "you have to take to a shop and get it running again. The friend told me this story and sold it to me. The1st sellerwho got sick was an old school hot rodder. Everything he did was hot rod period correct to this car. The boxed frame and motor now is what I found so far. He did run a negative ground 6 volt system. I do not know why but I kept it that way! The prior owner did not tell me anything about the motor except for this story.

Do you guys know how to search for this number. When I type it into casting number search engines it comes up blank.

So far the clearance is fine! Thanks Ed for your help

[P15-D24]

It's definately a 265 Chrysler six unless the crank has been changed. Flathead six engine stamped C52/C53 and C54 = 265 six cylnder chrysler engine.

V-8 hemi's also are stamped C51, C52 ect but they are the 331 hemi V8. Kinda confusing to some I guess.

Does this engine have dual carbs and dual exhaust? Aluminum intake manifold? Overdrive transmission? Lumpy cam? Full flow oil filter? An old school rodder would have done this.

there should be a block casting date in the area of the dip stick

 

i can not link you to a thread concerning date stamping due to the recent "pairserver" change.

 

this was the old link: it is not going to work. perhaps someone can modify it.
