'64 Valiant SLANT 6 -rookie question (Chevy guy!).

Thanks. Thewy'll work, but that's just exaclty the kind of littled eetail tha ta Non-Mopare guy wouldn't know. Mightnot be a big deal (say I was switching the one where I'd have to frill it out - I'd pass, keep looking).

So it';s good to knmow.
Can't afford trial and error, buying a hole car to get the engine!
(and cars, especially cooler, rarer ones like Valiant wagons aren't as easy to sell as they used to be...especially once i remove the engine. SO I want to do a deal like that only if it'll work.
Anyway - on the 23 slant 6s in 1964. Not to pick your rbain with 20 more $s, but maybe I canfind this concisely online somewhere/ Have ot so far?

...Visually what is a good way to tell the 225 from the other?

I don't have orig. Mopar reference material, so without having to go get the #s and thenm ask someone before buying the cars, can youtell me how to at least tell with a casting # all the ones of a certain displacement would have, which it is?

...and Just to ID displacement w/ the #...where is it?
(Like with some GMs, like on a 327 you'll have the casting # on the bellhousing telling you it is a 327, and "this" horsepower.
Then a stapmed in # elsewhere with more specific info. like date, etc.. Just the fun stuff).

Then if it's not a 225 I can pass. If I can determine it is, I can further decode any other #s later once icollect some reference info..

Also - between the 2 displacements, the switch would be the same, baring the small complications mentioned?
THANKS!
