1964 V8 engine numbering

V8 engines in Avantis and trucks built on and after August 20, 1963 and all those in 1964 Hawk/Lark-type models were not serialized as before, but were stamped with an alphanumeric code (e.g., PK329) indicating car/truck model, displacement, and date of manufacture. The1964 Vehicle Model and Displacement Prefixes are as follows:

V followed by a letter and 3 numbers = Lark-type 259

VC followed by a letter and 3 numbers = Lark-type 259 (Canada)

P followed by a letter and 3 numbers = Hawk/Lark-type 289

PC followed by a letter and 3 numbers = Hawk/Lark-type 289 (Canada)

R followed by a letter and 3 numbers = Avanti 289

RC followed by a letter and 3 numbers = Avanti 289 (Canada)

RS followed by a letter and 3 numbers = Avanti 289 w/R2 supercharged

RSC followed by a letter and 3 numbers = Avanti 289 w/R2 supercharged (Canada)

JT followed by a letter and 3 numbers = Hawk/Lark-type 289 w/R1

JTC followed by a letter and 3 numbers = Lark/Hawk 289 w/R1 (Canada)

JTS followed by a letter and 3 numbers = Lark/Hawk 289 w/R2 supercharged

JTSC followed by a letter and 3 numbers = Lark/Hawk 289 w/R2 sprchrgd (Canada)

R3 followed by a letter and 3 numbers = Lark/Hawk/Avanti 304 w/R3 supercharged

R4 followed by a letter and 3 numbers = Lark/Hawk/Avanti 304 w/R4

3E, 5E, 6E, or 7E followed by a letter and 3 numbers = truck engine with displacement as shown above

The date of manufacture was indicated by the final four characters; a letter representing month, a single digit for the year (3=1963, 4=1964), and two digits for the day. The month is represented by a letter as follows: A=Jan, B=Feb, C=Mar, D=Apr, E=May, F=Jun, G=Jul, H=Aug, J=Sep, K=Oct, M=Nov, N=Dec. Additional digits preceding the date code indicate an export engine.


*Notes (As referenced in the main chart above)

1. Packard engine

2. Also used in some Police Marshalls

3. See discussion above of 1964-model engine numbering

4. Reported, but not confirmed

5. 5E number indicates a 259 HD truck engine; no breakdown by year available 1959-64

6. 7E number indicates a 1957-64 standard-duty 289 truck engine; no breakdown by year available

7. Chevrolet-design engines built by McKinnon Industries Division of General Motors, St. Catherines, Ontario

8. First 109 1966 V models w/standard trans built with left-over 1965 engines

9. First 481 1966 V models w/auto trans built with left-over 1965 engines

10. Only one R4 built, in a 1964 Lark-type

Engine number location:

  • 1951-52: on top, rear end of cylinder block, next to distributor.

Studebaker V8 engine: The Studebaker V8 was developed in-house in 1949-50 by the Studebaker engineering department under the direction of Stanwood W. Sparrow.   It was available in different displacements at different times.   Although some running changes were made during the period 1951-64 (e.g., converting to full-flow oil filter in mid-1962), all Studebaker V8s are essentially interchangeable, with the only major differences being bore and stroke.

Studebaker Corporation: Had a reputation for being willing to build anything to make a sale.   For example, the 289 engine was not offered in any Studebaker 1959-model passenger car.   However rumors persist that several such cars were made by special order, and based on some other one-of-a-kind vehicles Studebaker made, they may be true.
