Just spent the last hour or so searching the HAMB and other websites. I found the firing order for a 1952 Desoto Hemi (1-8-4-3-6-5-7-2) but could not find anything specific for a S16 1953 276 Desoto Hemi. I know in the SB Chevy world many years have the same firing order, but have no idea what's what in the Hemi world. Have much to learn...
Yup, clockwise 1-8-4-3-6-5-7-2. With #1 up on compression stroke, the oil pump drive slot should be facing in the 12 o'clock/6 o'clock position. When the distributor is intalled, the rotor should be pointed toward the front of the car in aproximately the 5 o'clock position...

I would urge ANYONE playing with Vintage Engines to get off the Damn computer and buy Themselves a couple Motors Manuals. They are more informitive and actually Quicker to track down Whatever you need to find out.
This suggestion will not be quicker than Google, but public libraries usually have Motors, Chilton etc. in the reference section. You don't have to buy anything and you don't have try and find a place to put the %#@ing thing when you're done.
Man, If ya don't have room for a Motors Manual ... Where ya gonna put the Car, all your collected Speed Equipment, Parts & Tools ?
Obviously spoken by someone alot younger than some of us who do not have / use / or even want the latest electronica......Oh, by the way, those 'places' are called bookshelves and any shop worth a damn will have several...............and they work when the power is out.......... When was the last time you actually read a book?? .

"buy-em books...whata they do, look at the pictures and chew on the covers..."
Hmmmm. Didn't realize my husband's thread would bring out such asinine behavior in someone. Not that Desoto would even care, but...1) I called a dozen places in a 45 minute radius and no one had a manual in stock, so I ordered one. 2) The tiny little library in our tiny little podunk town doesn't have motor manuals. Doesn't even have a recent edition of a basic encyclopedia. So we posted a thread on this awesome site we found, so we could at least start doing a little work on the hemi and try to get it to turn over. To everyone who gave real information...Thanks a bunch. It was greatly appreciated. Hey De Soto...Hope you wake up on the right side of the bed next time.
i have a 1956 motor manual from my dad will look up any thing you need I dont know how but you are supposed to be able to contact peolpe direct on this site
And this particular question is the poster child, since ALL Chrysler V8 engines (at least 1951-90) are the same.
It may be true also of most V8 engines. I think the flathead is the same if you counted the cylinders like the rest of the world.
BTW: "Taxable horsepower" is a method of assigning road tax fees, taken from the R.A.C. (Royal Automobile Club) method, which ignores stroke length entirely. The formula is B^2 × N ÷ 2.5 where B is the bore diameter and N the number of cylinders. For the 276: 3-5/8" × 3-5/8" × 8 ÷ 2.5 = 42.05
One more thing: the drivers side is numbered 1, 3, 5, 7 and the passenger side is 2, 4, 6, 8. The distributor spins clockwise. People with Fords screw this up all the time. Later on the 426 Hemi (and 440) did the counter-clockwise distributor thing... Same firing order though...
Thanks for the added info. We had never worked on anything other than SBCs, so wasn't absolutely sure. Wish that dang manual would get here! Appreciate the help.
+2 on the Motors. You need like a 50-51, a 58-59, a 65-66, and if you want to go newer one from the early 70s, to cover just about everything from the mid-30s to the most recent year in the book. Shop around, I've paid as little as $5 in a thrift shop and seen them for sale for as much as $40. I'm sure you can find them by the dozens at Hershey or Carlisle. I would have thought all DeSoto hemis are the same, they don't usually change firing orders on a whim since it means new crank and cam if nothing else.
