Engin identification

How do I tell the difference between a 318 and a 340 engine?I pulled an engine from a 70 satelite.Always thought it was the original 318 4bbl.Now I find that it is not the original.So I am wondering if it is a 340 4bbl instead.

The first thing to check would be the casting large numbers on the side. There will be a long series of numbers, then a dash followed by the engine size, and then another dash followed by a single digit (revision I think).

If it happens to originally be out of a 70 Challenger it might be mine...

I will look this morning thanks...There is some chance it was from something like that because the transmission was e (I think ) which could have been out of a challenger

.Always thought it was the original 318 4bbl.

I don't think 318 4bbls were made in USA ( just down here in Venezuela )

[Troy]

Well, I'm missing my transmission too. Any way, there should be some stamped numbers on it too in various places.

You could get a 4 bbl on a 318 here - but not in 1970. My 73 Barracuda had a 4 bbl but I know it wasn't original. Since this car has had some modifications I wouldn't count on anything being exactly like the factory made it.

troy is droolin   is this possible that the lost combo has been found

The engine serial number stamped on the front of the block just below the drivers side cylinder head will show the displacement.

Well it is indeed a 318 4bbl...sorry I wish it would have been your engine.I will check the SER. # too Maybe it is someone else's engine.It has a factory cast 4bbl manifold on it and looks to be original (dont look like it has been apart)

What's the casting date on the engine? It should be near the part number that you already found.

Starting in '78 I think. Diplomat cop cars had them for sure. I read it on Allpar a while back when I was researching my car but I don't have the link handy.

I forgot the numbers at my shop  but promise to post them tomorrow.I will also look for date codes as well.I can say that the first numbers I seen just below the head on the drivers side of the block were PM 318 R then the SER. number.

318-2x4 in '57 and '58
318-1x4 in '59-62 and '78+

PM= Built at the Marysville engine plant
318= displacement
R= Regular fuel

The number following the 318R will include the build date, post the entire number and somebody will decode the rest of it.

thanks

The number on the block just under the head PM 318 R 23312120 the numbers on the side of the block 2538030 318 8

[John_Kunkel]

PM 318 R 23312120

2331 is the build date December 15, 1967 so it's a '68 motor.

2120 is the sequence number, the 2120th built that day.

This complete serial number is unique to this motor.
