Engine stamping.

[TheCouzin]

Hey all.

I am looking for the vin stamping on the block of my 79 440. Cast in 78.
These are the numbers I have gotten so far.

Passenger side casting numbers 4006630-440-4
Just above that casting is the date of 8•7•78

The only stamping I have found is on top driverside pad by distributor those are 9T440E
9 21

Any help? I dont see any stamping down by the oil pan/transmission at all. No evidence of stamping there.

Thanks

Right side of the block just above the oil pan midway back.

It is probably a truck, RV or industrial engine, as car 440 production was supposed to stop in 78. If you can't find a VIN stamp, then there probably isn't one.

It's a motorhome motor

I checked there. Also nothing.

It's highly likely motorhome mills had no vin

It's highly likely motorhome mills had no vin

But Its A 440!!!!!!!!!!!!!!!!

The previous owner did say it was from a Motorhome. But I thought it would still have a vin. Thank you.

The pictured engine is a 440, built at the Trenton Engine Plant, as a 1979 model. The engine was installed in an MBL300, MBH300, or an MBH400 front section chassis, or provided to a builder for a Class A motor home. These engines were not stamped with a vehicle identification number by Chrysler.

If the engine is still as assembled from Chrysler with its originally installed 4006452 heads, and they use 5/8" hex, tapered seat spark plugs, it was originally a 440-3 premium heavy duty engine. Otherwise, it is the 440-1 standard engine, with standard 4006452 heads, similar to 1976 - 1978 passenger cars.

Passenger car production of the 440 and 400 stopped after 1978. The 440 engine continued in 1979 in the aforementioned applications. It was ultimately replaced by the 446 cubic inch International Harvester gas engine in some 1979 and 1980 applications.

Replacement engines built before and shortly after 1979 for warranty or other uses were typically not stamped with a build year digit. In 1994, I purchased one of the last remaining new Chrysler replacement 440 short blocks. The identification pad is stamped with only "5 20" and "440". Its casting date is 4-20-1978.

AND, looks like I'm seeing the heavy side reinforcement characteristic of a cold weather block. Most likely a cast crank, but excellent stock item for building, IMO. (like any factory block, only more so).

These engines were low compression engines. The pistons are down in the hole. They were made for pulling not so much speed. Unless you take the pistons out and replace with some near deck height. Or throw a turbo on it.

The build sheets for the engine from previous owner said 10.27 compression. 3.75 stroke and 4.35 bore.

This is all about how it's milled, the current pistons, and the current head gasket and maybe even the current heads. For that matter the current cam comes into play there as well. Certainly does not sound like any factory pieces are still inside that block.....

I assume you are asking about the VIN, "just cuz" ???? I'm sure there were no Hi-Po motorhomes out there in 78-79 lol.

Yea me and my buddy with a 66 coronet were curious. I just picked up this car and am figuring things out. Its been fun learning about it. Heres a photo from the top.

My assumption was that it was just a stock engine... Thats a bit more than the stock late 440 would have been. So its a good thing it was built.

Yea the dyno sheet shows 542hp and 574tq.

All 440 production at the Trenton plant stopped after the 1978 model year. 1979 motor-home engine installations were from the thousands of 'banked' engines stored in the warehouse.
