Dodge truck engine id

[Brad47]

Can anyone one tell me what engine I have here ? My guess is 251 or 265 but am unsure 

I bought it shrink wrapped on a pallet and it was fully rebuilt 

[Brad47]

Forgot to mention that all I was told was it was from a Fargo pickup

I would measure the head to see if it is 23" or 25"

I do not know if engines in Canada are identified differently then USA ..... Using your numbers on this site I would guess it is a 46-48 Dodge car 218 or 230 CI

Is interesting that the field for cubic inch is blank on D25 .... yet the number lands in the middle of 230 CI engines ..... I do not know what that means.

Measure the head to determine 23" or 25" then measure the stroke and would tell you if it is a 218 or 230 assuming it is a 23" engine.

I have a 49 Dodge truck and the engine # starts with T for truck.

D is Dodge car.

P is Plymouth

It’s 25” and all I was told was it came out of a Fargo pickup

If it is 25 inch it could be one of several sizes 237 up to 251  I dont remember if there was a smaller than 237.  If you have the little plug over I think it was the last cylinder you might be able to using a long rod turn the crank till you come upon bottom stroke and then turn it up till it stops climbing carefully.  you have to measure carefully and I would do it with a long smooth rod one guy turns wile the other holds it straight up as there is mabe 1/4 inch between some of the different stroke lengths.  The Canadians used the Dodge trucks for phone service up until about 1968  you should have a date stamp near the distributor hole look for that?  If you get a length I can look it up for you.  Bob Harrison

There is a 218 also. Different exact CI than the 23" 218. One is like 217.8 and the other 218.1

Wasn’t a D25 an import version of the Plymouth P15 in Dodge trim? If so it’s likely the 25” version of the 230 CID engine. It may have come out of a Fargo, but it would have originally been in a Dodge car.

also, the canadian blocks were 25", not 23".  so the length isn't going to be of much use in identifying the size.

Head appears to be off. Easy enough to measure bore and stroke. No guessing involved.

[Brad47]

Thanks guys when I get down to the shop and I’ll measure bore and stroke and back to you 

thanks for the help

Bore and stroke work out to 220.73 CI.

I would say that it is a .020 over 218.
