How can you tell if a block is from a 440 6-pack motor?

Without the rest of the engine parts it's just a 440 block.

ok , now that we have scared the guy off possibly 
..
question to the thread starter ..
do you have a block or a complete UNMOLESTED shortblock ?
Or are you looking for one ? ... if you are looking for one they are easy to find , how may you ask ... check the price

All you need is an F440 HP or HP2 with the date code you think is correct. you could even goes as far as getting one with a VIN that is from the same plant that your car was built. there is absolutely no difference between a 440 non hp block , HP block or HP2 block other than the stamps ... and the PRICE

Correct me if I am wrong, but I thought that the 6 pack motors had 4 "eyebrows" in the pistons ? As in valve reliefs. I realize that this involves popping a head off, but is this information correct ?? I am interested in this answer also. I have a 72 Sat (parts car) that came with a 440HP & 4 speed. The motor is supposed to be out of a 6 pack car. It has the 6 pack bottom end , it has the correct damper. The funny thing is , it is possible. This car was pieced togethor many years ago, with a ton of good parts, factory cassette deck, air grabber hood, front and rear spoilers , 2 72 RR grilles etc. Even came with a mint spare drivers door with a 71 6 pack RR vin attached to it .

I am pretty sure the motor home I got my 440 block from had a six pack.

I parted one out that had two six packs, but they were both in the 'fridge.
Lucky me.

You're correct; there are a few things (like the valve reliefs) that are unique to a 440-6 but it's irrelevant unless you KNOW the engine hasn't been changed or rebuilt in the last 39 years.
OTOH there is no such thing as a "six pack bottom end": all HP motors starting in '70 used those rods and damper......and as it's already been said, there is nothing unique about the block itself.

So.. all 70+ 440HP engines have "six pack" rods and the elliptical "six pack" damper?

Yep, what John said......which is why the term "six pack rods" is the biggest misnomer in Mopar history.

And to those enthusiasts on a Mopar learning curve, the above discussion does not apply to the '69 440-6 and 440 Six Pack.
Rods, pistons & balancer are the same used on the 440 Commando and 440 Magnum.

If I understand this bulletin correctly, in late 1971 the 440 engine got different pistons and different crank.

Re: HOW TO TELL IF ITS A 440 6-PACK BLOCK - 03/26/09 11:51 PM
The bulletin reads in part:
"A new piston will be incorporated into production on the 440 C.I.D. standard engine late in 1971 production.This piston is lighter than the early piston so requires a new crankshaft.
Severe engine vibration will result if the early crankshaft or piston is used in these engines. The engines will be identified with the letter "C" on the identification pad on the top, adjacent to the left block and tappet rail as follows:"
....shows engine serial pad with stampings and goes on to list pn's for pistons and crank.

My buddy is doing a semi restoration on a '70 Charger R/T SE. The motor was a warranty piece that's never been out of the car, obvious by the fact the block is bare metal whereas the heads, intake, oilpan, bellhousing are orange.
Strangest thing is there were 7 six pack rods and one standard.

It says Std. 440, so it is about the non-HP versions.

Best way is to look at vin tag on dash, crawl under car with a good flashfight, might need a rag with laquer thinner. If stamping on motor looks good and matches last part of vin, crawl out from under car and yell out "yippee I just found a 440 6 pack block".

very INTERESTING , for years the mASSES have been drinking Galen's koolaide and saying that the C denoted special crankshaft for 440-6 engines ... NOT

Does the stamped date on the engine ID pad by the distributor on a 440 refer to the build of the short block or the long block? At what point did Chrysler stamp the spec. info on that pad?

I guess it depends on the particular build , if it was a complete engine then it would be of the long block , if it was a partial enngine then it was of the short block ...
