man im so freakin out of my mind right now one thing after another!!!! im in the process of rebuilding a 351 cleveland.. well it was a 2 barrel carb and manifold on it when i took it apart. its a 2 bolt set up and the prob is that the casting number is d2ae-ca.. i was told that it was a 4 v not a 2v but was also told that the casting number might be wrong but i checked it twice...... i got these parts for a 2v and now am some what stuck with them.. what should i do and if so is the number right and i need to look for 4v stuff?

Not sure what you are asking, but the only thing different between 4V and 2V is the heads and intake, the blocks are the same. There are some 4-bolt Cleveland blocks, early CJ and Boss 351 had them, late CJ and HO were 2-bolt. The D2AE-Ca just designates a 72 or later block(D2).

So you don't get taken again, 4V heads all have a "4" cast right next to the corner of the valvecover rail where it meets the corner of the intake, any other letter or # is a 2V head.

cool so even though the casting number says its a 4v cobra jet is it still a 4v block even though its got 2v heads and a manifold on it... so the things i got will still work? nice thanks man....

The casting # you gave does not mean 4V, there is no casting # specific to 4V, that is why I said look at the corner of the head.

Likely what you have based off that casting # is a 72-73 2V engine.
