Hello,
My truck came with a different engine than original - I've located these numbers on the block - can anyone tell me how to read these numbers - and what do they mean?
E7TE-6015-DB
-or- ----- can't tell if its a 6 or a G ----
-G015-DB

any specs on this number would be greatly appreciated.
Thank you.

 

E7TE Means that it was made in 87 and it's a Truck Engine.

On most ford parts there is series of numbers and letters, and they begin with a letter generally. The letter stands for the decade. C is 60's, D is 70's, E is 80's, F is 90's and now the letter is G for the 2000's. So C8 means 68 etc... pretty simple once you know that. As for the rest of the numbers, I will let someone else field that.

 

Any cast-in number is the part number for the casting. Later parts often continue to use an earlier design casting. E7 does indeed mean 1987 -- which is the first model year this casting was used.

T means truck - but the part designed for the truck can be and was used in other applications as well, in other engine families. The 300 was in truck use only, so no issue there.

The second E means that the Engine Engineering Office had design responsibility (B means Body, P means automatic transmission, I have forgotten most of the others).

6015 is an engine block, without main bearing caps. Just for trivia, 6010 is a block with bearing caps, 6009 puts bearings and some plugs in it.... 6000 is a complete engine. These are called base part numbers and are unique to the function of that particular part.

The suffix reflects ongoing design change -- D is the fourth major change for that prefix and base, and B means the second minor change. Many of these changes take place in preproduction and prototype stages. The design always starts with AA, but it is possible that AA, BA, and CA were never actually manufactured.

So -- we know that the block was designed for a truck, to be produced sometime after 1987.

 

Thank you - anything else - like - hopefully heavy duty parts installed?

I would like this engine to last me a long time.
Thanks again guys.
