Need help identifying Dodge HD Truck and Engine
Hi everyone, this is my first post on this site. I am posting some pictures of an old HD Dodge Truck, with what I believe is a 413 C.I. Flathead Six. The flat on the block does not contain ANY of the letters/numbers that I have found anywhere on the net with regard to the "T" designations. There is no registration or serial number plate. Any ideas? Thanks.

That's a beast. I've never found one of those around here, which surprises me because you would think a few would have found there way into farm country, but I guess the farms and trucks around here was smaller in the day. What are your plans for it?

Since posting this, I ran across a youtube video of a 1946 2 1/2 ton Dodge firetruck, a WJ-57, and the engine and truck are most likely one of the smaller 12 port flatheads, like a 281, as the one in the video. What is visible in the video of the engine is the ONLY match I have found. The 413's I have discovered all had twin carbs and exhausts, while this has one carb and one exhaust outlet. I have a bunch of parts from the engine on ebay, in my store, arccoinsandautocollectibles, but if anyone is interested I'll sell through this site, if it is permissible. Thanks, Doug

I've heard of a 331, but not a 281. Flat Head Engines: Plymouth-Dodge-DeSoto-Chrysler Six and Eight

Yep, 281 and a 306 school bus engine were also 30 inch flatheads with 12 ports. The 281 was normally a "T136" designation, 1946-47, in WJ 55-59 vehicles. 331 was a "T135" in 46-47 WK 65-69 and WR 65-69 vehicles. Info on the 281 and 331 comes from "T Flathead Six Engines" on the net. The info about the 306 comes from a guy who got at me on ebay who should be an administrator on a Dodge Flathead site. He knows his stuff.

I have seen a couple of trucks with these engines, and Tom (posting on 'inliners.org') has one at his home in northern Nevada.
He had a lot of discussion about that engine on that forum... Big Six Pics | MOPAR | Inliners International Bulletin Board |

Here are some pics...
This fuel tanker truck was in residence at the rail workshop at the Sierra Nevada town of Virginia City, while this is Tom's engine: One half of the twin-carby setup: |

That would look great in an extra large speedster...

Need help identifying Dodge HD Truck and Engine
Hi! This is my first post on this board. My understanding of the 413 flathead six is that it was only used in Dodge trucks for 1 year, 1954. They were a force to be reckoned with from what I've been told. My Grandfather owned one and, believe it or not, other truck drivers would come to my Grandfather and offer to run loads for free to get a chance to drive it. Nothing slowed it down, full load, hills, nothing. It was the only one in the area. Another man would borrow it from time to time if his truck was down for any reason. Even he said it was the fastest thing on the road. . The grillwork on the fenders was supposed to signify it was a 413, 6 cyl. Here is a pic if it when it was new, hope it comes through. It was sold to a company around 1960 that hauled mail. The truck, at that time, had around 200,000 miles on it.

Yes, I do, Dick...
A thread where many rejected early posts and kept on asking the same questions! What a shame all the pics are gone. |

It been a long time since I've posted!
Some notes on the 413 engine... They were produced only for the 4 ton model "Y" trucks 1953-1955. 1953 was the first 413 Dodge 4 ton truck engine. Total production of the 413 trucks is approximately 3500 units for all years 1953-55. 281, 306, 331, 377, and 413 all are Nickel Chrome Molybdenum cast blocks.. Starting in 1950 the first 4 ton model "Y" truck came out with a 377ci. six that used twin carbs and dual exhausts thru 1952. Then in 1951 all 306's, 331's and of course the 377 had the twin carbs and dual exhausts all factory installed. Only exception was the 1951 thru 1953 B-3,4 model R bus with a 229" WB . That model bus... Dodge's biggest.. had a 306 ci engine with only a single carb and single exhaust. I have one of these buses.. only one I've ever seen. Parts for any of these "Moly Block" engines?...nope unless you spend years looking or have the parts made like I've done. There's a set of valves and valve springs on ebay currently. nothing more. These "Moly Block" engines complete with accessories including the air brake compressor less trans weigh in about 1170 lbs. I have four of these heavy series trucks with the 306, 377 and 413 engines. Know these engines and trucks well. Last edited by bugmenot; 07-30-2021 at 08:10 PM. |
