Casting number ending in 8830 says it's a 75-78 and the botched casting date looks to be a block that was cast on the 23rd day of 78. Can't read the month but most likely was early in the year but the J on the pad says it's a 73 and I'm finding that the 8830 blocks were cast earlier than 75. And where was he taking it to get 50 bucks in scrap price?

I dunno -that year could be a "73". There's a list on the 440 Source site that shows that as a '73 number.

I am somewhat skeptical of moparts' chart. It looks like they have that block as 8330, and uh, 65 and 66 max wedges?

And Moparts has the '73 - '78 as "8330". Typo?

I would go with the "J" for 1973. Pad looks clear.

Get a much better shot of the vibration damper. 73 was a changover year for forged vs cast cranks. Offset weights or odd shapes would mean cast, you MIGHT get lucky and get a forged.
According to what I read, there will be a stamped "E" near the block casting date indicating cast. A good pic of the damper will be more definate. Unbolt and remove the pulleys.
Oh, and pull the valve cover and get a shot of the cyl head casting number. 452?

What do you guys feel it is worth it turns over without issues.

66Satellite47 · Jan 31, 2020

The knowledgeable guys on here should chime in, would a '78 block have a "HP" stamping? Can't think of any real late HP offerings. $250 or so for all that seems good. The cost to do what you want with it is what you need to figure.

Understood I hope to make a nice motor out of it nothing crazy I can throw about 3k at it .

73-78 440, the casting date says 1/23/73. I thought it was 78 at first glance, but looking harder and with the "J" code, I say it is a 73 under all of that casting blob... The balancer looks like a neutral balanced job, so I would assume the crank is forged.

Heck your already ahead ....... the intake is worth $100.
No matter what the date code is its at least a 40 year old 440 and who knows whats inside it until you open it up.
Just like Christmas :thumbsup:

Is there a vin number on the pad above the oil pan? That would show the model year, assembly plant and sequence numbers.
The balancer and the J says early 73 to me. I'm thinking the cast date is 1-27-73 and the assembly date is Feb 22nd.

Nice score.

good grab!
I'm more amazed that
Pete Chargervert didn't find it first!
he owns most of the Mopars in Rhode Island..

A 440 can rev more than 3000 rpms.

Start by finding a good reputable shop that knows HP builds. $3K gets you a nice moderate build.
