Info on 1949 230 Flathead 6 with 8 bolt rear crank flange? (Plymouth truck)

['41 Fat Bottom Girl]

A friend is trying to find out if he has a lower production or a more common engine, or any pertinent info on this version.

I don't have enough info or knowledge to help him.

What he has is a '49 Plymouth truck that has a 230 with an 8 bolt rear flange and will be trying to locate a crank and some rods.

He thinks these were made from 1942 to 1954. Was this a special engine (crank?) for trucks, or was it used for cars too?

Engine ID is P-1484929-41

Any insight would be appreciated! I think cranks are getting harder to find, so any suggestion for sources would be terrific too.

Thanx Much!

I read a note somewhere to the fact that the early FD trucks utilized the crank carry over from the early 218 powered Dodge car...as they were also 218 engines...for that fact thru 47 the Plymouth based engines were in all the small 1/2 trucks...

Fantastic! Great info, guys! This looks to be his crank.

Do you think there would be anything special about the connecting rods, or should they be same as the standard 230?

I sure appreciate this continuing education I'm getting, too.

First thing is this:  we need a pic of that truck.  The 49 ply is one of my favorites.  Lots of them cannibalized for the bumpers on customs.  But, I've never seen a truck of that year.

 

On the crankshaft question, I have an engine that is destined for my 56 1/2T that has an 8 bolt crank.  It is a 230 that came from a 56 Plymouth according to the stamped numbers.  I am using a flywheel from a 59/60 Dodge pickup, also 8 bolt.  So there may be a lot more sources than you think. 

 

My rods are a mismatched set from more than one engine.  I know because the stamped numbers are not one of each number 1 - 6.  It was rebuilt in the past by a commercial rebuilder that just grabbed 6 230 rods at assembly time, probably because of one or more spun bearings.

My Hollander only shows 1 230 rod.

No such thing as a 49 plymouth truck unless someone customized a sedan. Engine serial # is a 42 plymouth car and should be a 218 and have a reg 4 hole crank pattern. This is a lot of mismatched parts

Sounds like he gave me some bad info when he called me. Very confusing (?) I will talk with him to get a better idea of what he has. I have not seen the truck . I will try to get better info to see if we can better sort out what he has.  

I understand he has the engine torn down and he sounded very certain describing that 8 hole flange on the crank.

Thanx!

Doing some hunting, I found this statement-

The 230 and the 218 are very similar motors, the main difference being the stroke, if you put a 230 crank and rods into a 218, you will have a 230.  

 

If true, it suggests the engine was rebuilt before, sometime back in its history with a 230 crank and rods.

Thanx!

I bought a used flathead from a old forklift that had T- numbers and when I looked it up it turns out that # was built as both 218's and 230's from the factory. Used mostly in military apps. Probably not the original forklift motor either!

 

So to know,  it was I could either measure stroke or check the crank casting # that Is what I did and it showed  it was a 230 ci. motor at least as bought. As built?? Never will know.

 

Both as original  CI motors can easily be either. No changes in the blocks/ heads at all. The truck motors as far as I know used the same parts -rods/etc. as the cars. Cams? Has been asked here many times and no for sure answers.

Thanx for the info. This is what we think this is:

Might be a '39 or '40 by the headlights and grille. The seller is looking for the pink slip (title) before he gets the body. He said paid pink slip, so it might have been from California last time it was running. Engine is being looked at before he goes ahead with the sale, was sitting outside for many years and rusted up. Body is apparently in good enough shape to be salvaged. They say the internals don't seem too far gone, but was definitely rebuilt some time past because the crank was .040 under and can't be used. It was rebuilt with a 230 crank and rods in the 218 engine.

The info on a source for the 230 crank was perfect- thanx Conn47D24! And Young Ed for the engine ID and you others for your help. And Egge has the 230 rods. Jury is out on the cam. Will be pricey for this project, but so far looks like it might be back on the road again. I hope so.

Glad you all could help him and hope he joins the forum and sends pix of the renovation if he goes through with it.

This is an amazing forum, boys and girls!

Best Wishes to all for a Merry Christmas, be safe, and enjoy your families.

Motorheads Forever!

39-40 truck have the same grill. 40 has additional stainless -3 bars on each side horizontally at the top of the grill. If stock 39 has bulb and reflector headlights and 40 has sealed beam with little parking lights on the top.

My 56 Plymouth engine is a 230 with a six hole crank flange.  When I put it back together I used the 56 flywheel with the 46 clutch and transmission.  It now has the 56 trans 46 clutch and 54 overdrive. With the stock 46 drive shaft.

Newbie here.  I thought the 8 bolt cranks were used in Fluid Drive cars/trucks.  So they were also in (some) trucks...?
