Is it possible they used the old 383 RB block and just made a 440 out of it?

I considered that, Polaraco, but it didn't make sense. The RB 383 has value in its rarity. It would seem to me that it would be easier to try to pass off a regular 440 as a HP?

This is going to drive me NUTS!

You are not crazy...you clearly have a 440..not a 383.
 
Regardless of what the stamping on the pan rail says, which as stated above, 68's did not have the same identification number there as the 69 and later did.  So it is more than likely a sequence number and/or like suggested it was a "rush out the door" friday job or a "Hung over" monday stamping.

I suppose an easy way to tell if you have a B or RB is to check the intake manifold casting number. If its a 440 number then you have the wider RB block. There was an RB 383 block but I think it was only made in about 1958 or so.

Reminds me of the story at the factory when, at the completion of the shift, one worker found out they hadn't been making Darts that day.... and a whole bunch of cars were made with "Valiant" on one fender and "Dart" on the other

Well, once again, thanks to the GREAT group of folks her, I feel a whole lot better!

Today I am going to try to find every number I can on both the engine and transmission. Regardless of my success or failure, I am no longer concerned about whether my engine is a 440 or a 383.

Oh, Fury440, My intake casting number is 2806178. Galen says:

2806178   1967   B-body   440   1-4 barrel   HP
2806178   1968   B- & C-body   440   1-4 barrel   All
2806178   1969   A-, B- & C-body   440   1-4 barrel

It was this that let me get a good night's sleep last night.

I'll report back all my findings.

Thanks again to everyone for your help. It is truly appreciated!

The best way to be sure of what you've got is the Block casting# on the side of the block.   That's the  -430# asked about.    The date it was cast is on the side also so you can make sure of year if in doubt.

They can be awfully hard to see if the Exhaust manifolds are still there.   I have no doubt yours is a RB motor if it has the flat pad adjacent to the dist.

OK, I have some good news and some bad news.



The Good News is I was able to get the numbers off the block and here they are with their translations as I understand them:



Block Casting Code
253643010 = 1966 thru 1972 440RB
(can someone explain the '10' after 2536430 to me please? The same casting number was found on both sides of the block)



Casting Date

1 25 68 (found above the casting code on the passenger side of the block)

YUP!!!! She's a 1968 440 fer shure (I get a little redneck when I'm excited). That made me feel a whole lot better.

Here's the complete stamping info on rear pan rail (below starter) that caused me so much worry:

PT383R24093217



Translation

PT = Trenton Plant (where 361,383,413,426w and 440 were built)

383 = Displacement (WRONG)

R = Regular Fuel (WRONG)

2409 = March 2 1968 (10,000 day calender)

3217 = 3,207th engine built that day (that's seems like an awful lot of engines to me)

I don't know how much, if any, of that stamping is correct as far as the date and sequence number, but that's what's on there.

Now for the bad news.

While under the car, I got the transmission numbers too. This is what I found stamped on the driver side of the trans just above the pan:

PK3515845I   3307   0151

and this was stamped on the passenger-side of the housing:
1C108703

If Galen's correct (and he always is) this is the 151st 1971 A-727 TF built Aug. 17 1971.
(sigh)
So, this is clearly not the original transmission. Oh, well. that doesn't really bother me too much. It's the engine I care the most about and determining that is is definitely a 68 440 engine made me very happy.

So that mystery is solved and I now now my trans is out of another car. Oh well, c'est la vie (jeez, I must get French when I'm a little depressed)

OK, I'm standing-by. Let's hear your thoughts!

Probably a rebuilt trans.....yours was sent in as a core. My original trans was converted to a manual valvebody, reverse shift pattern trans, so I have another on standby.....I am not too concerned with trans #'s matching. A 4 speed modern trans would be nicer 

Now, let me shake ya up a little! It COULD HAVE BEEN possible to have a 383 B engine with a 440 manifold.....IF the previous owner put on a set of Mopar Performance aluminum Stage 6 heads and painted them engine color. Those head's angle need a 440 intake on a B or spacers on a RB. If this had been the case, I wouldn't have any trouble sleeping at night....a stroker 383 with Stage 6 heads would certainly make up for #'s not matching!

You just won't let me off the hook will ya? ;-)

No, after finding the casting number 2536430, I know it's a 440, although that stroker 383 doesn't sound too bad either.

Any thoughts on why I seem to have two extra casting numbers (see my previous post)?

That is very likely.
1963 to 1966 Canadian built Valiants were actually Darts with Valiant trim.With the exception of the Barracuda which had some minor trim differences.

Well I'm glad ya got that figured out U.H.!!! and I learned something too, the fact that I AM crazy and a 413-440 is a taller block than a 361-383. But I'm glad you have a 440 for sure!!
Sounds like it was a monday/friday kinda stamping deal.
