  1. The ratio should be stamped between the 2 carrier bolts that are parallel to the left (drivers side) axle tube. Go to the “Pilothouse Knowledge”site. Click on to the 1948-53 truck parts book. Click to the rear axle section. The photos show you where the axle ratio’s are located for all the relevant truck models.
  2. It doesn’t matter whether you have a 23” block or a 25” block as long as you use the crank “And” rods from one and install them in another block of the same size they will work.
  3. No Problemo. Good luck with your project.
  4. Oil capacity is 5 quarts without oil filter, with oil filter 6 quarts.
  5. If your talking about displacement my Motors truck repair manual 1936-42 lists the T-40 as a 218.06 (3&3/8x4&1/16) L Head.
  6. Ok, we need to figure out just what you are talking about. You have an early 3/4 ton WC-51 with the 8.75” ring and pinion third members right? You switched out the 5.83 r&p’s for 4.89’s then right. Good luck finding one set of 4.30 r&p’s let alone two. Your best bet would be to locate 2 good used 4.30 8.75” third members and bolt them right in. This ratio was used in all 1ton dodge trucks from 1940-1952-53. The DU route van also used this ratio. The side gear spline size was changed in the civi trucks from 1945 onwards so make sure if you purchase a post war third member that you have the right axle shafts to go with it. 3.91 and 4.10 ratios were also available, but those are very rare also. You need to keep in mind that in going with a lower numbered ratio you will gain more top end speed but lose power going up hills. Believe me I know. I am running 4.30’s in my 1/2 ton WC with 900-16 tires. I have a 25” 236 Flathead in it which is mostly stock. It cruises good at 55-60, but anything more than a moderate hill and it losses pulling power quickly. Those 900-16’s are a heavy tire and wheel. Things to think about when switching out ratios in these old trucks.
  7. Thank very much. I appreciate it. Have a nice day.
  8. Any chance you could give me the contact info of the person you bought the tranny from? Thanks.
  9. Hi Jomani, Would you be interested in selling the transfer case shift lever set-up. I could sure use it for my WC-12 transmission swap. Thanks
  10. I this the motor that came with the 1 ton WD you purchased?
  11. Finally got around to painting up the CC 695798 Aluminum head. I had it shaved .060 and will install a steel head gasket with it. This should give me a compression ratio of about 8:0:1. It is also quite a bit lighter than the cast iron Spitfire head presently on the IND-7. Not as eye catchy, but I like it nonetheless. I will have the Spitfire head shaved down to get an 8:0:1 ratio also and keep it as a back up in case the Aluminum head takes a big pooper on me.
  12. Hello Jomani, What is the letter or lettering to the left of the of the engine serial number. Is T, S, IND or maybe a rebuilders letter(s). What part/casting number is on the head. Does your transmission have the drain plug parallel to the bottom of the case or is it facing at a downward angle. Downward angled plug = non-synchro. tranny, parallel plug = synchro. tranny.
  13. Perhaps some gunk was not cleaned out of the block properly and it has let loose and plugged an gallery somewhere in the block.
  14. If they are like the ones on my 41 Military 1/2 ton, parts are real hard to come by. There are internal and external repair kits. Again very hard to find. You might try the GM forums. Special tools are required to take them completely apart. You can have them rebuilt, but it is expensive. I had mine rebuilt by A-1 Shock in Santa Ana, CA. Figure around $200.00 per shock. Good luck. Love the looks of your truck.
  15. That Spitfire and Tranny you have looks like it was installed in a military 1/2 ton WC 4x4. The Power Wagon has a 2 speed transfer case and this set up shows one lever so hence, a single speed transfer case. Also they used the brake and transfer case mounting bracket off the original WC crash box to fabricate the set you show. That tranny is also not a fully synchro one. Only 3rd and 4th gear have synchro’s. The NP 435 was the 1st 4 speed Dodge Installed tranny that had 2nd, 3rd and 4th gear synchro’d. I have the same transmission as the one you show which I plan on installing in my WC-12 military. I will study the photos you have and try to replicate the modifications that were made. Do you have any Idea what displacement the Spitfire is? What are the numbers stamped on the raised pad just below the head on the left front of the block? That should give you an Idea what size it is although you never know, sometimes the crank and rods were switched out among the same sized engine blocks. Good luck on your projects.
  16. The above listed speed and rpm data is assuming you are running on 750-16 tires and wheels with a radius of 16.25” or 32.50” diam.
  17. Do you know what third member ratio you have in your 1Ton? Never know, it could have the rare 3.91 ratio. I like the 1 ton you have there. Are all your wheels the split ring type? My eyes may be deceiving me, but it looks like your left front wheel is a 1 piece wheel with no split ring. Maybe I’m seeing things. If you have the standard 4.30 ratio third member in your truck, the 265 would be spinning at 2445 rpm’s at 55 mph in 4th gear. That’s about 67.75% of the engines 3600 rated rpm’s.
  18. Procure the Bunn and Brownell Dodge Pick-ups History and Restoration Guide 1918-1971 book. In the back of the book it explaines on how to modify the grooves in the main Bearing shells etc. It’s a great book. Highly recommend it. Published in 1991.
  19. Just going by what the Brownell and Bunn book says. Congratulations on your 3000 RPM 1900 trip. Again speaking for myself, I would not run a flathead at more than 75% of the rated RPM’s.
  20. Welcome to the forum. That is a Canadian built truck. Most of the 25” flatheads were rated at 3600 RPM’s. Wanting to run at 3000 RPM’s is asking a lot of these flatheads without doing oil system mods. I wouldn’t run these motors much past about 75-80% of rated RPM’s. That’s just me talking and like they say, “talk is cheap”.LOL. What model command car do you have? I have a ‘41 WC 12(Salad). Again welcome to the forum.
  21. Well here I am back on my easy chair writing to you all. The 236 was cold from it’s last run over 8 Hrs ago. Turned key on, 2 pumps on the gas pedal, inserted DPCD starting crank #568949 and on the second compression crank she fired right up. Gotta love those Mopar products. “It’s Mopar or no car” as they say.
  22. Hey guy’s, thanks for reminding about the hand crank. When I go out this afternoon to give the WC-12 a road run, it’s going to be, “Handcrank starting time . I think since I re-engined the truck from the 23” 230 to the 25” 236, I’ve only done it once. Will come back with the results, either from the comforts of my own home or the emergency room. LOL.
  23. Believe those are the letters of the foundry. NH I’m guessing would be North Hamtramck?
  24. Is your cab a prewar or postwar cab? The full water fall lines on the dash make it out to be a prewar cab unless the glass is causing a reflection. Nice work on installing a PH box on the WC frame.
