I got the 65 Dodge Coronet 500 home in one piece and put it on the lift. Now I wanted to try and verify if the car, engine, transmission and rear axle are truly numbers matching. It’s much easier to verify numbers matching cars after 1968. Those cars have partial VIN numbers of the car on components like the engine and transmission. Earlier engines like this one did not have partial VIN numbers on the engine, but they had casting dates and assembly dates. You had to check the block casting date, the engine assembly date and the car’s build date, in that order, when attempting to verify if it is numbers matching car.
The 426 street wedge engine was only used in 64 and 65. The engine ID stamp on the pad located at the front of the engine shows an engine assembly date of 10-16 or October 16th. The “A” on the pad, in front of 426 indicates 1965. The first step in trying to verify if the 426 wedge engine was original to the car was to remove the starter to reveal the casting number and casting date of the engine block. This car had a Shipping Order, or planned delivery date of 203 or February 03 1965 on the fender tag. My thoughts are if the engine was cast in 1964 it was most likely assembled on 16 October 64 for use in an early 65 model car. If that was the case after the engine was assembled it would be stamped with an “A” for 1965 rather than a “V” for 1964 because it was scheduled for a 65 model year car, and the assembly date would be 10-16 of 64. I removed the starter and the casting date read 4-10-64. So, the 426 wedge engine block was born in 1964 and used in a 65 Coronet 500.
