Hi, well I am sure this same question has been asked a lot but I am going to ask it again... I have a 460 block and I am rebuilding it, I went to put in my new crank bearings and the ones on the ends didn't fit SO now I am questioning the year of it I was told it came out of a 77 LTD but I am not so sure now the casting # is D1VE-A2B
if I got it right the # near the lifters is...
2H14
The heads are at Eastco getting rebuilt so I dont have the ##'s off those. Any help would be nice, Thanks

That block was cast August 14th/1972

A2B means that after that block was first designed in 1971 it went through several revisions before it was cast in 1972.

 

Thanks for the info, got any ideas about why the bearings for the crank are about 1/16Th" to narrows? and its just the ones for the ends

 

Well I found it in a book at the library, the crank bearings with the flange go in the #3 spot not 5...

 

Anyone know what the block came out of then? If it was cast in 72 i could assume it didnt come out of a 77 LTD, right?

 

The V (3rd character) designation means it was designed for a Lincoln.

However, that engine could go into anything that had a 429/460.
The D1VE- meaning it was designed for a 71 but received some changes for 1973 because it was cast in August start of the 73 car production,& this would mean it was produced as a 460.

More than likely it came out of a full size car like a Lincoln,Thunderbird, Large Mercury.

 

I guess I may be asking an obvious question but i just want to know for sure. So the engine is out of a 72 or maybe 73 model vehicale?

 

It was used all the way through '78.

 

a block that was cast in 72 was used until 78? What did it sit in a warehouse some where?

 

No, they did cast them for annually projected production runs. That would have had to have been a giant warehouse. The DIVE casting number, with a few minor engineering changes, was used throughout that period for all 429/460 engines, as there were virtually no changes to the engines other than cam and c/r (pistons) from '72 through '78. Exceptions were dropping the CJ/SCJ, DOVE and DIVE blocks, after '71 and adding the PI, DIVE block, from '72-74. The PI became a standard production engine in '75.

 

I have heard a lot avout D0VE blocks and heard those are the Cobra and super Cobra jet blocks, what makes them differernt from the D1VE block? I am under the impression you can get a lot more horse power from a D0VE block over a D1VE block and that the heads on a D0VE block are a lot better. Can you use SCJ heads on a D1VE block? Sorry I know there are a lot of questions here and they are all mixed up...

 

The SCJ and some CJ engines had 4-bolt mains from DOVE and DIVE blocks cast with thick main bearing webs. Both blocks, can't remember the engineering codes on DOVE but DIVE is DIVE-AA, were machined as 2 and 4-bolt blocks.

All blocks, regardless of main bearings, will produce the same hp. The difference is the 4-bolt will live a lot longer when hp exceeds 650-700.

All 429/460 heads are interchangable on 429/460 blocks.

 

so to make my D1VE-A2B block into an Super Cobra Jet engine, all i need is a set of 429 SCJ heads?

 

No. That's a thin webbed block. AA has the thicker webs in 2 and 4-bolt configurations. The CJ/SCJ also had better rods and the SCJ had a solid lifter cam with adjustable valve train.

 

Is there such a thing as a 460 SCJ engine? And what kind of vehicales would I need to keep an eye out for to find a D0VE block or any other block that I could make into a 460 SCJ eninge?
