Phurray Posted January 6, 2017 Report Posted January 6, 2017 Hello all. I'm a new owner of a 1953 Dodge one ton and am in the process of ordering a new data plate for the truck. It is Canadian built and according to the serial number it is a DH-2 126" wheelbase with a 228 ci engine. On the data plate there are spaces for maximum weight and horsepower. Can anyone tell me what the gvwr and horsepower would be for this truck? Thank you very much for any help offered. Quote
T120 Posted January 6, 2017 Report Posted January 6, 2017 (edited) The Max Gross Rating for the DH2 is 8000 lb . AMA HP Rating is 27.34 ( Reference Manual -Truck Shop Manual WM-4283 - Chrysler Canada) Edited January 6, 2017 by Ralph D25cpe Quote

Merle Coggins Posted January 7, 2017 Report Posted January 7, 2017 They didn't put he AMA HP rating on the tags. It should show true HP. 1 Quote

The AMA HP figure I listed for the DH2 was in the Licence Data in the manual...I don't have the HP figures for the 228. cu in Data Plate....My Fargo 1/2 Ton,(218 cu in) with an AMA HP rating of 27.34 has two figures listed on the data plate, 82 HP at 3400 RPM and 97 at 3600 RPM - Edited January 7, 2017 by Ralph D25cpe Quote
Phurray Posted January 7, 2017 Author Report Posted January 7, 2017 Thank you Merle. I just researched A.M.A HP (a term i wasn't familiar with) and from what I can see there is no relation between A.M.A. and true HP. Hudson Terraplane defined A.M.A. as..... "A mathematical formula used for taxation in some states and involving only the bore and number of cylinders. It ignores stroke, compression, ignition, valves, cooling or other vital factors of engine efficiency which affect actual horsepower." Would you know what the true HP of the 228 is? Quote
TodFitch Posted January 7, 2017 Report Posted January 7, 2017 The A.M.A. or A.L.A.M.? I don't recall hearing of a A.M.A. horsepower rating. A.L.A.M. (Association of Licensed Automobile Manufacturers) was a trade group setup in the late 1800s or early 1900s to collect royalties on the Seldon patent. Basically a patent attorney filed an overall patent for a automobile in the late 1800s then used a number of procedural tricks to keep it from being issued until there were actual cars being manufactured then he went after them for royalties. Henry Ford fought that and eventually won. That did in the A.L.A.M. as a controlling entity in the automotive industry. But in the meantime the A.L.A.M. had setup a technical committee which came up with a formula for estimating horsepower based on the technology of the era (very slow piston speeds, etc.) The A.L.A.M. horsepower calculation was adopted by the National Automobile Chamber of Commerce (N.A.C.C.) and was used in literature about cars for a lot of years there after. My '33 Plymouth lists a N.A.C.C. horsepower rating of 23.43 and also a brake horsepower (bhp) of 70. I believe that in some states N.A.C.C. horsepower was considered the "tax horsepower" and licensing fees were based on it. Edit: It looks like the A.M.A. was a successor to the N.A.C.C. (which was a successor to the A.L.A.M), so I guess something could have had a A.M.A. horsepower rating, probably with the same 1900 vintage calculation as the A.L.A.M. and N.A.C.C. used. See https://en.wikipedia.org/wiki/Automobile_Manufacturers_Association. And it appears that the calculation used for that was the same as was used in the UK but there it resulted a generations of long stroke engines built to reduce the tax burden to the owner. I don't think enough states in this country used the tax horsepower enough to have that effect on manufacturers. Quote
T120 Posted January 7, 2017 Report Posted January 7, 2017 In early owners manuals inside the front cover under License Data you will find the AMA HP listed ... Quote

I guess I am just used to looking at things for older cars: The A.M.A. came into existence in 1934 (apparently the N.C.A.A. reorganized). So my "Instruction Book" does not list a A.M.A. value but it does list a N.C.A.A. value. Quote
T120 Posted January 7, 2017 Report Posted January 7, 2017 Interesting - my 36 Desoto has the License Data inside the front cover with the AMA HP rating...I looked at the 1940 Studebaker owners manual I have and it lists the HP (NACC or RAC Rating), Quote
Darkrider Posted January 7, 2017 Report Posted January 7, 2017 From what i recall reading the Data plate on my B1D which has the 228 i believe it was rated at 89 Hp. Quote

ggdad1951 Posted January 8, 2017 Report Posted January 8, 2017 Vintage Power Wagons sells the data plates Quote
Phurray Posted January 8, 2017 Author Report Posted January 8, 2017 I'm getting mine at machineplatesonline.com Quote
lonejacklarry Posted January 9, 2017 Report Posted January 9, 2017 Can anyone tell me how a data plate is attached to the firewall on a '54 C1 B6? Quote
