440 identification inquiry

[Northern Australia]

Hi all

As we do from time to time, I found myself looking at an interesting vehicle that I could become attached to for a time should the universe align in a particular way.

I only have very limited details available, but is it possible to determine from the cast numbers in what type of vehicle the engine was originally installed in or built for?

It is a 1977 engine and I am mindful many (perhaps even most) 440s around that time were low compression engines installed for heavy duty work rather engines that were intended to perform. The owner doesn’t know what type of vehicle the 440 was taken from.

Or were all 440s by 1977 relatively sedate compared to those manufactured in earlier years?

I will drive the vehicle next week, and though I should do some due diligence before hand.

Thanks in advance to the Mopar community.

The block should have the VIN stamped into it if it's from that vintage and that will tell you what it came out of. I'm not sure where that was stamped in 1977; maybe someone can chime in here. Otherwise, check the top of the block near the oil pressure sensor or down along both sides of the block above the oil pan.

IF it is even stamped, a '68 VIN will be on the back of the block by the oil sending unit.
69 and later will be on a pad on the passenger's side of the block.

A partial VIN can narrow down what the engine came out of as we know what plants built what cars for each model year.

After that, if you have a large enough data base, you can bracket the VIN to determine what make (Plymouth, Dodge, Chrysler, Imperial) or Model (Satellite/Coronet/Charger or Fury/Polara) was installed. After that, you may have to know specific applications for certain engine assemblies i.e. 340s only came in certain makes and models or a 383 or 440 HP vs non HP. Determining what an engine came out of can be done if you have the right info.

To go along with the VIN or partial VIN stamps on the block, also look at the casting date and casting number on the side of the block. The casting date will pre-date the production/machining/assembly date of the engine, possibly up to about 6 months, as I understand it.

By that point in time, any of the OEM 440s and 440HP engines (cars and light trucks) would have been factory-rated at 8.2CR. We also know that that is the "blueprint spec", but most had a wee bit more deck height and a wee bit more cc in the combustion chamber, normally. ALL of which would allow for future machining as needed in rebuild situations.

IF the engine is totally unmolested/un-rebuilt, then the OEM factory specs can apply. IF the engine has been rebuilt . . . no such guarantees as to what was put into the motor when rebuilt.

Just some thoughts,

Thank you all - as always, very helpful.

I find it interesting that people don’t ask where a replacement engine came from. As a result, the information isn’t passed from one owner to the next.

It seems most people are most interested in the displacement figure alone and presume performance can be reasonably estimated from just that metric. As we know, there is a bit more to performance than displacement alone, and the performance of some engines (including the 440) changed a fair bit over time.

Thanks again from Daniel in Darwin
