Help with number decode on this engine...

[dspaulding70]

I think the number on the engine is 2536430 8

[Arthu®]

2536430 is the block casting number for any 440 "RB" engine produced between 1966 and 1972.

What about these as well

2806178 is a intake manifold for a 1967 440 1-4 Barrel HP engine. It was an engine build for a B-Body and the part number is 2843031.

How does this engine look to you all?  I realize that you really can't tell anything until it gets torn apart but just curiuos if you see anything of concern.  Thanks.

One more picture

Yup, there is some pretty good information in there. It's 3:35 AM here and I just finished a 10 page essay and don't have to get up until 8 so I thought why not be of some help to someone

As of how the engine looks, it looks rusty. But like you said you can't really tell anything until you pull it apart. A lot of old engines look like that, it really depends if it was turned over from time to time, was there water in the engine when it was put away, was there oil in there or was it completely empty. Can't really tell anything from those pictures.

A 6178 manifold would be the standard 4-bbl manifold for any 67-69 440-4bbl including 69 A body and 67-69 B or C bodies. Used on both standard and HP applications.

It looks like the manifold casting date matches pretty well with the engine assembly date. Looks like this came out of a "C" body too.

[dspaulding70]

Where would the date code be located on the block?

Where would the date code be located on the block?

The D on the pad tells us this was for a 68 model year car.
The 11 18 on the pad tells us the engine was asembled Nov 18, 1967.
There is a date code of what appears to be 10 (Oct) XX 67 on the manifold. I can't tell what the middle day numbers are.

There should be a casting date on the block also.

[Arthu®]

I stand corrected.

That engine looks like it's been sitting outside unprotected for a while, seeing the rust condition inside the intake and on the spark plugs. Also, if it has in fact been in the elements uncovered, having an open hole in the valve cover won't have helped either. Either way though, you'll be rebuilding it, correct? So as long as nothing major has happened you should be fine. 

[dspaulding70]

In looking closer at the engine, it was not painted orange.  Since this supposedly was a Plymoth engine, did the not paint the blocks orange?  This one appears to be blue.

Thoughts?

[Arthu®]

I might be wrong, but I don't believe there was a difference in engine colors between: Dodge, Plymouth and Chrysler. The only difference were the names I believe.

A 440 for the 68 model year should be turqoise (sp?) which is kind of blue. The 440HP engines weren't painted orange until 1969. They were painted turqoise from 1964-1968, orange from 1969-1971, blue 1972-1974.

The difference in color had to do with whether it was the HP or Lo-Performance version of the 440.  E85 LoPo 440's were mostly installed in C-bodies, and were painted turquoise in 1969 (although you could get the orange-painted E86 HP 440 in some C-bodies also).

Every 1968 C-body engine i've seen is turquouse

D440 on the pad and it has the c-body valve covers

[dspaulding70]

So do I have an HP motor or not?  I am getting confused

[RD]

if there is not a "HP" stamping on your ID pad by the valley pan, then you do not have a HP motor.

[dspaulding70]

Where is the valley pan you mentioned?  Sorry, I have not heard that term before.

Take a look at the picture I posted with the yellow circle around the production date. If the engine was assembled as an HP engine, you would find the HP stamp on that pad. No HP on the pad = no HP engine.

That is because every 440 was turqoise in 1968, the difference is in 1969, at least that is what the white books say.

[JimShine]

I do believe there was an exception. I think some Dodge 1969 440 HP's that were AC equipped were turquoise.

[69_500]

I had always thought that the only exception to the painting an engine turquoise in 69 was the 383 cars, that had A/C that were very early production pieces. IE there are 2 Survivor 69 Superbee's that go to many of  the major Mopar shows that both have theirr blocks painted turquoise.

[dspaulding70]

Can someone post a picture of the HP stamp on the block?  I thought all 440's in the Roadrunners were the HP.  I guess I may be wrong.
