[michael.warshaw]

If you have one pm me, i need one, thanks. Mike w

[michael.warshaw]

will be a quick sale through paypal, no checks, thanks mike w

[RobertKB]

I don't have one as they are all long blocks in Canada but it might be an idea to repost the actual date code you are looking for.

VPW likely has what you want although pricy but maybe that is the way to go as you have asked here before with no luck.

Michael,

There really aren't any significant numbers on the heads, although I think there may be some cast code that tells exactly where and when it was made. If someone wanted to criticize my car that deeply I think I'd smile inwardly that it was the only thing he could find wrong in the entire car, while outwardly I'd certainly be tempted to shove him by his throat away from my drive.

The important number is on the block, which is the engine itself and if you don't like the numbers you must buy a different block, and that's it in a nutshell. Don't worry about that crap and just get the beast on the road and more than just a few miles behind the wheel. These vehicles are addictive (which is why we're all here) and you'll never appreciate her like you will after a jaunt up the Rockefeller to Newburg, thence to New Paltz, and ease her back home. Spend a full day with it, have a picnic with someone as adventurous as you, and it will never be the same car to you again. Each time you take it out you'll come to appreciate it more. Most all of the piddly $#lt can easily be handled after you're on the road. Just drive it.

you are right randroid thsnks

As you may know, the Plymouth head has a large letter "P" cast on

the top, just behind the throttle linkage pivot. So, if nothing else,

you can be sure it's a Plymouth head if the letter is there.

The Dodges had a "D" on them. My engine is a 1957 Plymouth item

with a 1950 Dodge head on it. Works fine. My outlook is - that's

not a big deal. It would be interesting to see if a judge at a mopar

show picked up on it.

Again, Boff my Plymouth heads are conspicously naked of markings. The 46 and the 56.

[BobT-47P15]

Hmmmmm...............

[Don Coatney]

My Spitfire head (a Chrysler only head) does not have any chrysler specific markings on it.

My Desoto head also does not appear to have engine specific numbers cast into it. However as I am far from home I cannot take any fresh pictures.

[Flatie46]

I thought the "P" stood for PERFORMANCE or POWER.

[michael.warshaw]

was the spitfire different?

[garbagestate 44]

Different only in the sense that it has "Spitfire " in relief with those cool lightning bolts. Long block only.

[Reg Evans]

I have 4 heads loose here right now and 3 of the 4 don't have a letter. The one by itself does have a P on it.

[RobertKB]

Reg, looks like two are for the external by-pass engine and two for the internal, the one with the P on it being for the latter. You need to find some engines for those heads to go with, and then some vehicles to put them in!

[greg g]

Jeez, heads must be like oil filters................

[Reg Evans]

No....Oil filters are much lighter.

[Reg Evans]

Reg, looks like two are for the external by-pass engine and two for the internal, the one with the P on it being for the latter. You need to find some engines for those heads to go with, and then some vehicles to put them in!

Hey thanks Robert ! I'll get on that right away.

[michael.warshaw]

is the head that reg has correct for a 218 out of a 47?

[james curl]

The one with the P cast in it is an internal by pass head and will not work on a external by pass engine. The bump out on the front of the head must match a bump out on the block. The early engines are external by pass and do not use a head like that. The P-15 is not an internal by pass engine as far as I know, the internal bypass came out in 49/50 cars.

[michael.warshaw]

well im still on the hunt then.

[greg g]

Both my early 46 engine, and my later 56 engine are internal bypass. The 48 Dodge engine I bought some parts from was an external set up, So when they were made seems to have had little bearing on the whys and wherefors of the bypass system installed. So in your searching do you know which type your block is?? It seems this would be more important to determin than whether there is a P cast upon it.

[james curl]

After looking at one of my original service manuale I find that I was incorrect in my statement about the internal by pass engines. According to my manual if you have a P-15S,P-18, or P-20, Special Delux models only are external by pass engines. Models P-15C, P-18 and P-20 are internal bypass engines. I do not know if the P-15C,P-18. and P-20 which are not special delux are just Delux trimmed cars and not Special Delux trimmed cars. Are the P-15, P-18 and P-20 Special Delux all S cars and the Delux P-15. P18 and P-20 all C cars? It appears that the P-19 two door sedan and the P-19 3 passenger coupes were all Delux models while the P-19 All Metal Suburan was made in Delux and Special Delux trim. The same cars in the P-17 series were all Delux only cars. So Michael it looks like you will have to determine which type of engine your car has and find the approiate head, The P-15 coupes all came in both Special Delux and Delux models. The only P-15 models offered in one body style only were the Convertible Club Coupe and the Station Wagon which were offered in SpeciaL Delux Trim only.

And to further complicate matters, the aftermarket cast aluminum heads were/are applicable to either Block. Which begs the question "Whats the difference other than the bump out and various an sundry foundry casting marks?"

Some one needs to do some head sleuthing, both of mine are bolted in place with the exception of my swiss cheese Edmunds.

[Young Ed]

The early 50s truck engine I got from Merle had both internal and external setups going. And then no thermostat just a core of one that might have slightly slowed down the flow.

Interesting. I wondered why the engine in my 1950 truck and the one in my '50 parts truck both have internal bypass yet that engine, that should be newer, didn't. Someone did some cobbling I guess.
