Ford ltd 2 1977

It has eight bolt holes, even if one bolt is missing.
Your block number is D7TE-A3B. It's an engineering number, and it means the block was cast for the 1977 model year, and A3B shows how many times the design was changed since the design was new. It does not include the second number, which tells what the exact part is, in this case an engine block, as it's obvious it's a block.

 

So what engine do I have???

 

A 351M /400, but look at the VIN, it will tell you the correct displacement. Thing is, the two displacements use the same exact block, unlike the 302/351W, which have different blocks. So you should still be able to get the correct dizzy.

 

This is what my VIN looks like btw.Sorry for so many questions but a biy lost.thks for all the assistance. Highly appreciated.

 

Yeah, fifth digit is the engine, but, Ford in its Infinite Wisdom, designated the VIN code to both 351 CID engines, or at least they did in 1974 (I used to have a '74 Squire). So, you tell them you have the '335' series 351 CID (it means a 3.35" bore depth, IIRC, or deck height, something like that). That should get you the correct distributor, or electronic ignition unit.

 

So, my 78 F250 had a 400 D engine in it. What differentiates it from a 351M400?

 

If your rig's VIN code is 'S,' it came from the factory with a 351M/400. But if not 'S,' then you may have the older 400; you would have to shinny under your rig with a flashlight, to see if it has the dual bellhousing patterns or not.

 

It blows my mind that Ford never really standardized this and made it more obvious\understandable to the average Joe. GM had a VIN designation based on engine size and family at least...

 

I agree. For what Ford standardized, their powertrain engineers sure dropped the ball on standardizing design, as well as VIN designations. The VIN code 'H' in the mid-70s, noted 351 CID, but you have W, C, then C replaced by M.

 

LOL i still cant figure it out and the manufacturer for the electronic is determined to find out if its a C or W which i dont have a clue about

 

It is neither, it is an M. And if they still can't figure it out, give me the contact info and I'll call them on your behalf.
And just so you know:
"C"=Cleveland Foundry
"M"=Midland Truck Foundry (although they made M engines for cars also)
"W"=Windsor, Ontario, Canada Foundry

Engines are not always ID'd by the foundry they were cast at, but the 351's all had to be differentiated.

 

Thanks a Bunch. Let me pass the details to them and see what they have to say.
You have been a huge help and I'm glad to have met you. Cheers

 

Do you think this will work ?

 

Says it fits. $170 is not a bad price for a standalone unit...I assume the electronics are contained in the "right side" (as the picture is)?
