With Ford, they began using this form of block casting in the late 1950's. They assigned each decade a letter which begins the casting number. 1950 began the coding with letter 'B'. Each subsequent decade received the following letter. The first number after the first letter is the year of that decade in which the part was modeled for.This means that your block casting number d4de6015aao is for a:D = 1970's4 = 1974This motor has a block casting number for 1974.
What year and size engine has casting number B1378704E
That is the intake manifold casting number from a 1970 350 CI 300 HP engine.
The Chevy engine with that casting number was made in 1993.
if this is a GM motor there is a casting number on the top of the block behind the drivers side head,it is visible while the motor is installed on most vehicles,then all you need is a GM casting number book available at most automotive stores which also lists all engine component casting numbers and a range of vehicles they came on. Good luck
it is a 1969-1979 motor it was used in cars, trucks, and vettes
If it isn't a straight 6 you will have to find the casting number on the back of the block with the year and date. Most likely its a 283.
The Chevy engine with that casting number was made in 1993.
This size motor was manufactured from 1968 - 1976. In order to find the exact year there should be a number 1 high casting on the bottom left corner of the block.
