deciphering engine numbers

Here's my situation. the numbers BBC 1965 T0319IE
That's Tonawanda, March 19, 396/425 MT SHP (manual trans, special high performance).

I know that IF designates corvettes but IE is full size chevy, but which one?
Impala, Biscayne, Belair or can't a guy derive which particular model this engine was destined for?

Thanks,

Though big blocks got a partial VIN stamped onto the pad it doesn't include any identification as to body style. There isn't any way to tell that I know of.

Right, it just lists it as "B" Body.

The info is not broken down to which one.

Thanks guys, that's what I figured. Would be nice to know what it came out from a historical standpoint. Guess it's a dead end. I think I recall a brochure that even had them available in wagons too. Maybe not?

No other board or car information site that you could go to for this information? Perhaps someone else on the forum can direct you to somewhere or someone you can call?

Double check that.

The '65 396/425 with a Manual Trans in a Vette is "IF".

There are just no such records kept. Chevrolet had no productive reason to keep them back then. Maybe if they knew just how popular they would become, they may have. But I have to say that there is a whole lot of stuff out there, just not very particular ones like the OP is seeking.

Record Keeping

Chevrolet did maintain records that show how many L78's were installed in each full size model. However, that does not help you identify which model the engine came out of without a full VIN.

That is a fairly early block. It requires a grooved cam as there isn't a groove under the rear cam journal found on 1967 and up big blocks. The good news is if that was cast within the first four months of the production run (the 396 came out mid year with the 409 retained through the first half of the year) The block will have very, very thick cylinder walls because it was cast to be either a 409 or a 396 which differ greatly in bore size. If rebuilding it you can have the cylinder wall thickness checked to confirm allowing you to convert your 396 into a 427 or a 481 if you used a 454's four inch stroke crank. with the 409's bore size.

The engine stamped pad is as such.
5D162171 T0319IE

Tonowanda March 19th 396/425 Special high performance

5=1965
D=Doraville, GA
162171-?

Does the 162171 tell anything that might lead to indicating what style body?

There is no known additional information other than what you have already.

The mechanical solid lifter engine was only installed in race cars, so odds are it wasn't put in a wagon. Usually it was put in a stripped down, radio and heater delete two door Biscayne sedan body (because the sedan was lighter and stronger than the hard top body and the Biscayne was lightest body sold due to lack of sound deadening and other insulation). Most where painted white when ordered with that motor and transmission.

Thanks Dave, Just checking the pads and reading the numbers on some sites and thought you might know more than they do. Your a wealth of knowledge and who knows, you can teach an old dog new tricks.
Is a vin possible from any of this?

The 5 denotes the 1965 production year.
The D is for the assembly plant located in Doraville on the NE side of Atlanta GA. It was primarilly a Buick and Olds assembly plant that made the full size Chevy only for the 1965 model year.

The sequence 162171 is your partial VIN. It is unique to the car that the motor came out of.

The sequence number was preceded by a 1 that tells you it was made by the Chevrolet division of GM; followed by the two digit code for the series (what you want to know, such as was it a Biscayne, Bel Air, Impala, Caprice, or Kingswood), Then you get two more numbers that tells you the body style (if it is a two or four door sedan, or a two door or four door hardtop, a two door sport coupe, or a station wagon or a convertible). all of these numbers and letter assembled together would make up your full VIN when it was all strung together.
