Howdy my casting code on the block is D7TE-A-2-B. Ive found out what the D7TE stand for but what does the A-2-B maen. Well thx for ne info.

 

That is a suffix demoting change-ups to the original design.

Ie: - A is the first design

- B is the second design.

Then all the way through part of the alphabet until it gets a 2nd digit

AB
A2A


etc

 

Thx umm got another quest. My trucks a 79 F-250 Coustom casting number on block says its a 77 engine. Meaning not the original motor the guy i got it from says its a 351m whats the easiest way to figure out exactly what it is. As in if its a 351M, 351W, or 351C. Its my first truck project and i dont know a whole lot about engines but u got to start somewere. Thx for the info

 

351m-351c-351mc are all cleveland blocks m & mc have oil system and smog mods the c doesnot visually the same 351w is a winsor blockand looks like a 302 narrow valve covers standing allmost straight up .m-mc- c and 400m-mc are fat and are round toward the rear odds are you have the 351 is an m as w requires a different bell housing and m was the motor in 79 pickups

 

My trucks a 79 F-250 Custom casting number on block says its a 77 engine.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Actually, the Number cast into a part is the design number for a particular year,engine,model of vehicle.

Just because it has D7AE doesn't mean it is from 77.
It means that part was first designed in 1977 for a large Ford car but used on a truck.
It it was originally designed for a truck, it would read D7TE -

Now that we got that out..


To tell the exact date of casting, you have to look for the date casting code, this would be either a 3 digit or 4 digit number.

ie: * 8M21 * which translates to Dec 21/1978 which is going into a 79 vehicle.

Okay ,,,,Do ya dig ?

 

OH- HO!!!! i see well that helps out alot thx ill be sure to come back for nefurther quests

 

Actually, the 351 Windsor, Cleveland and M are three distinctly different blocks. The 351M and 400 share the same block. Except for a very rare few, these engines have the large bellhousing pattern as used on the 429/460. They use the same heads as used on the 351C, resulting in occasional confusion in identity. The 351W, as stated is similar to the 302 but with a higher deck height. The 351W and 351C share the "small block" bellhousing bolt pattern with '65 up 289 and 302 V8s and the 240/300 Sixes. The Clevelands had a relatively short production period from '70 thru '73 and were never offered in the trucks.
