[WANTED] Looking for a set of 340 X heads.

[Dave Wilkinson]

I need a set of stock original X heads for my 1969 340. On the wish list is E castings, but that's probably a little over the top. I'm in Champaign, IL and I'll drive significant distance to pickup.
Thanks

Never heard of “E” castings.

I heard and seen of;

X, J, O, U & Z.

Date

 

[Dave Wilkinson]

I could be wrong..... but, I thought this was the casting.

 

[cudamark]

Yup, letter suffix after the casting number indicates approximate year and related casting mold. There may be an actual date code cast into the head too.

 

[Dave Wilkinson]

Exactly!
That's why I'm looking for an X head and the E would be a bonus for my restoration.

@Dave Wilkinson , a guy on FB marketplace has a set. He’s in Somerset PA.

 

[Dave Wilkinson]

Thanks!
I'm not on FB, but I'll have a buddy check it out!

 

[oldkimmer]

Make sure they have the 894 casting number. Cause in 1970 the X head was a 915 casting. But it also says 360 on a runner. Kim

That's very useful information that I did not know!
Thank you!

I have this set for sale in Southern Wisconsin.

 

[Dave Wilkinson]

Hello!
Nice pictures! Thanks!
Where at in Southern WI?
The heads look like they have been worked in a machine shop. Do you have any documentation on their health?
Price?
Thanks,
Dave

I have 2 sets , I will check them for e casting.

 

[Dave Wilkinson]

Thanks!
The X Is the big deal. The E is only the date code to match my car, and not that big of a deal.

 

[67Dart440GT]

I sent you a PM with info.

After reading this post I looked at a pair of X heads I have saved for a later project and one is 2531894 E the other is 2531894 A . I presume E is 69 so what is A ? Can't be '65 . 340's didn't exist till late '67 for the '68 production. Any thoughts ??

Can u post a pic of the A. Maybe it’s like the 340s we’re only used in cars till 73. But I have seen 1977 year blocks. 340s were in boats and other equipment. And for warranty purposes. Kim

Regardless of the -letter, the heads will likely have a 4 or 5 digit date code on them. I forget at the moment

 

[Bennoel 10]

Here's what I found

 

[Bennoel 10]

One more

 

[Sterling]

The bare set I have, are supposed to be cleaned and magged. But they have a D letter

 

[crackedback]

The head date code that @Bennoel 10 posted would be a solid date for a mid november and on 69 model year car.

09238 = Sept 23 1968 casting date.

The E that you are searching for is not a date code, it's the core box used for the casting. Irrelevant to the actual casting date/production year.

Thanks for the info!
I appreciate all the help.
Picked up a set that are in great shape and delivered to the machine shop today.

Curious as to what a set (pair) in great shape are worth ? And if they were complete or without valves, springs etc. Thanks

 

[Dave Wilkinson]

Good Morning!
Fair question... this set was inspected at a machine shop. New guides, freeze plugs, and inspected for cracks. Heads are bare. Also, money back if they showed cracks at my machine shop.
$500....
