Blank front pad on 440-6

[The70RT]

My 440 is blank on the front pad. The side has casting number 3698830-440-6. Date code 6-29-73. It was a dealership factory replacement according to the original invoice (Jim Clark Chrysler Plymouth Topeka, KS) i still have from late 73 when they installed the $169 short block. Should the pad be blank? Im kinda wondering why a 6 pack motor was installed? Maybe was in stock already? The invoice shows rod out. If the engine was savable I guess it could still be out there somewhere?  They never put my vin number on this block though.  It does have the 6 pack rods and is a steel crank. Is that the only benifits from having this engine besides a stronger block than what originally in the 70?

They didnt produce a 6-pack engine after 72.  Also, the strength of a 6-pack block itself is no different that a 4bbl block of the same casting process. The sixpack strong points come from the internal components and the intake and carbs.

When you say the front pad is blank, you mean the pad to the driver's side of the distributor?  No 440 stamped on it?
And, the VIN pad on the passenger side block oil pan rail is also blank?

Unusual.  Typically there are numbers or letters of some type on the top pad.

One block in the garage has the "W" & "T" at random/upside down on the top pad for Water Test, and an "S" denoting service/warranty block, same as per Galen's book notes for service/warranty blocks.  Block's oil pan rail is blank.  This same block has no assembly date, so I presume it was sold as a bare block.

Another block in the garage has the" W" & "T" at random/upside down on the top pad for Water Test , and an "S" denoting service/warranty block.  Block's oil pan rail is blank.  This block has an assembly date on the top pad, so I presume it was sold as service/warranty short block assembly.

Keep that receipt!  Big deal to collectors and your resale value!

Right no markings on the pad left the dist. And pan rail is blank. The casting number 3698830-440-6 means what? it is on both sides of the block.

The casting number is for a 72-78 440. The '-6' means it is the 6th casting core revision.

Thanks. I guess i could have did my home work. I had the car for 30 years and have just now started the resto. I rebuilt the engine in 1980 after looking inside it probably didn't need it. I bent a pushrod then and went ahead and tore it down and added a slightly larger cam then. and discovered the 6 pack rods?
